Tuesday after Trinity 5 (Isaiah)

1Make a joyful noise to the LORD, | all the earth!*
          2Serve the LORD with gladness! Come into his presence with | singing!

3Know that the LORD, | he is God!*
         It is he who made us, and we are his;
we are his people, and the sheep of his | pasture.

4Enter his gates with thanksgiving, and his | courts with praise!*
         Give thanks to him; | bless his name!

5For the LORD is good; his steadfast love endures for- | ever,*
         and his faithfulness to all gener- | ations.

The Covenant Renewal at Shechem
1Joshua gathered all the tribes of Israel to Shechem and summoned the elders, the heads, the judges, and the officers of Israel. And they presented themselves before God. 2And Joshua said to all the people, “Thus says the LORD, the God of Israel, ‘Long ago, your fathers lived beyond the Euphrates, Terah, the father of Abraham and of Nahor; and they served other gods. 3Then I took your father Abraham from beyond the River and led him through all the land of Canaan, and made his offspring many. I gave him Isaac. 4And to Isaac I gave Jacob and Esau. And I gave Esau the hill country of Seir to possess, but Jacob and his children went down to Egypt. 5And I sent Moses and Aaron, and I plagued Egypt with what I did in the midst of it, and afterward I brought you out.

6“‘Then I brought your fathers out of Egypt, and you came to the sea. And the Egyptians pursued your fathers with chariots and horsemen to the Red Sea. 7And when they cried to the LORD, he put darkness between you and the Egyptians and made the sea come upon them and cover them; and your eyes saw what I did in Egypt. And you lived in the wilderness a long time. 8Then I brought you to the land of the Amorites, who lived on the other side of the Jordan. They fought with you, and I gave them into your hand, and you took possession of their land, and I destroyed them before you. 9Then Balak the son of Zippor, king of Moab, arose and fought against Israel. And he sent and invited Balaam the son of Beor to curse you, 10but I would not listen to Balaam. Indeed, he blessed you. So I delivered you out of his hand. 11And you went over the Jordan and came to Jericho, and the leaders of Jericho fought against you, and also the Amorites, the Perizzites, the Canaanites, the Hittites, the Girgashites, the Hivites, and the Jebusites. And I gave them into your hand. 12And I sent the hornet before you, which drove them out before you, the two kings of the Amorites; it was not by your sword or by your bow. 13I gave you a land on which you had not labored and cities that you had not built, and you dwell in them. You eat the fruit of vineyards and olive orchards that you did not plant.’

Choose Whom You Will Serve
14“Now therefore fear the LORD and serve him in sincerity and in faithfulness. Put away the gods that your fathers served beyond the River and in Egypt, and serve the LORD. 15And if it is evil in your eyes to serve the LORD, choose this day whom you will serve, whether the gods your fathers served in the region beyond the River, or the gods of the Amorites in whose land you dwell. But as for me and my house, we will serve the LORD.”

16Then the people answered, “Far be it from us that we should forsake the LORD to serve other gods, 17for it is the LORD our God who brought us and our fathers up from the land of Egypt, out of the house of slavery, and who did those great signs in our sight and preserved us in all the way that we went, and among all the peoples through whom we passed. 18And the LORD drove out before us all the peoples, the Amorites who lived in the land. Therefore we also will serve the LORD, for he is our God.”

19But Joshua said to the people, “You are not able to serve the LORD, for he is a holy God. He is a jealous God; he will not forgive your transgressions or your sins. 20If you forsake the LORD and serve foreign gods, then he will turn and do you harm and consume you, after having done you good.” 21And the people said to Joshua, “No, but we will serve the LORD.” 22Then Joshua said to the people, “You are witnesses against yourselves that you have chosen the LORD, to serve him.” And they said, “We are witnesses.” 23He said, “Then put away the foreign gods that are among you, and incline your heart to the LORD, the God of Israel.” 24And the people said to Joshua, “The LORD our God we will serve, and his voice we will obey.” 25So Joshua made a covenant with the people that day, and put in place statutes and rules for them at Shechem. 26And Joshua wrote these words in the Book of the Law of God. And he took a large stone and set it up there under the terebinth that was by the sanctuary of the LORD. 27And Joshua said to all the people, “Behold, this stone shall be a witness against us, for it has heard all the words of the LORD that he spoke to us. Therefore it shall be a witness against you, lest you deal falsely with your God.” 28So Joshua sent the people away, every man to his inheritance.

Joshua’s Death and Burial
29After these things Joshua the son of Nun, the servant of the LORD, died, being 110 years old. 30And they buried him in his own inheritance at Timnath-serah, which is in the hill country of Ephraim, north of the mountain of Gaash.

31Israel served the LORD all the days of Joshua, and all the days of the elders who outlived Joshua and had known all the work that the LORD did for Israel.

Barnabas and Saul Sent Off
1Now there were in the church at Antioch prophets and teachers, Barnabas, Simeon who was called Niger, Lucius of Cyrene, Manaen a member of the court of Herod the tetrarch, and Saul. 2While they were worshiping the Lord and fasting, the Holy Spirit said, “Set apart for me Barnabas and Saul for the work to which I have called them.” 3Then after fasting and praying they laid their hands on them and sent them off.

Barnabas and Saul on Cyprus
4So, being sent out by the Holy Spirit, they went down to Seleucia, and from there they sailed to Cyprus. 5When they arrived at Salamis, they proclaimed the word of God in the synagogues of the Jews. And they had John to assist them. 6When they had gone through the whole island as far as Paphos, they came upon a certain magician, a Jewish false prophet named Bar-Jesus. 7He was with the proconsul, Sergius Paulus, a man of intelligence, who summoned Barnabas and Saul and sought to hear the word of God. 8But Elymas the magician (for that is the meaning of his name) opposed them, seeking to turn the proconsul away from the faith. 9But Saul, who was also called Paul, filled with the Holy Spirit, looked intently at him 10and said, “You son of the devil, you enemy of all righteousness, full of all deceit and villainy, will you not stop making crooked the straight paths of the Lord? 11And now, behold, the hand of the Lord is upon you, and you will be blind and unable to see the sun for a time.” Immediately mist and darkness fell upon him, and he went about seeking people to lead him by the hand. 12Then the proconsul believed, when he saw what had occurred, for he was astonished at the teaching of the Lord.

Isaiah the prophet was born of the tribe of Judah, and for this reason he calls the Lord Jesus his cousin. His name means “the salvation of the Lord.” He wrote a marvelously beautiful account of the Savior of the world. Mary must have been reading the seventh chapter, on the virgin mother of Jesus, when the angel Gabriel came to her. The forty-third, fifty-third, and sixty-third chapters shine forth from this book like pure jewels. Jerome said, “To me, Isaiah seems to have composed not a prophecy, but a Gospel.” Augustine said, “He could better be called an evangelist than a prophet.” In his youth, Augustine asked the bishop Ambrose for advice on what book in the Bible to read first. Ambrose replied that he should begin with Isaiah, since Isaiah would supersede all the others in his prophecies of Christ. … It is a wondrous miracle that he named Cyrus or Cores, the liberator of the Israelites, by name two hundred years in advance (44:28; 45:1). Josephus writes that because of this, Cyrus was kind to the Israelites. Manasseh is thought to have had Isaiah cut into two parts with a wooden saw. Chrysostom (Conc. 33. super Matthaeum) lists the trivial reasons for Isaiah’s death: (1) He compared Jerusalem with Sodom and Gomorrah. (2) He boasted of having seen God, contrary to Moses in Exodus 38. (3) He said, “Call upon the Lord while He is near” (55:6); but God is near to all who call upon Him, etc. It happened to Isaiah according to the proverb: “If you beat the dog, you can expect to be bitten.”

“Do not My holy name disgrace,
Do not My Word of truth debase.
Praise only that as good and true
Which I Myself say and do.”
         Have mercy, Lord!

Prayer of the Day
Lord God, heavenly Father, through the prophet Isaiah, You continued the prophetic pattern of teaching Your people the true faith and demonstrating through miracles Your presence in creation to heal it of its brokenness. Grant that Your Church may see in Your Son, our Lord Jesus Christ, the final end-times prophet whose teaching and miracles continue in Your Church through the healing medicine of the Gospel and the Sacraments; through Jesus Christ, our Lord. (1049)

Isaiah, the son of Amoz, is considered to be the greatest of the writing prophets and is quoted in the New Testament more than any other Old Testament prophet. His name means “Yahweh [the LORD] saves.” Isaiah prophesied to the people of Jerusalem and Judah from about 740 BC to 700 BC and was a contemporary of the prophets Amos, Hosea, and Micah. Isaiah was a fierce preacher of God’s Law, condemning the sin of idolatry. He was also a comforting proclaimer of the Gospel, repeatedly emphasizing God’s grace and forgiveness. For this he is sometimes called the Evangelist of the Old Testament. No prophet more clearly prophesied about the coming Messiah and His saving kingdom. Isaiah foretold not only the Messiah’s miraculous birth (Isaiah 7:14; 9:6), His endless reign (Isaiah 2:1–5; 11:1–16), and His public ministry (Isaiah 61:1–3), but most notably his Suffering Servant role and atoning death (Isaiah 52:13–53:12). The apostle John’s description of Isaiah, that Isaiah saw Jesus’ glory and spoke of Him (John 12:41), is an apt summary of his prophetic ministry.
