Old Testament: Exodus 3:1-15

¹Moses was keeping the flock of his father-in-law Jethro, the priest of Midian; he led his flock beyond the wilderness, and came to Horeb, the mountain of God. ²There the angel of the Lord appeared to him in a flame of fire out of a bush; he looked, and the bush was blazing, yet it was not consumed. ³Then Moses said, “I must turn aside and look at this great sight, and see why the bush is not burned up.” ⁴When the Lord saw that he had turned aside to see, God called to him out of the bush, “Moses, Moses!” And he said, “Here I am.” ⁵Then he said, “Come no closer! Remove the sandals from your feet, for the place on which you are standing is holy ground.” ⁶He said further, “I am the God of your father, the God of Abraham, the God of Isaac, and the God of Jacob.” And Moses hid his face, for he was afraid to look at God.

⁷Then the Lord said, “I have observed the misery of my people who are in Egypt; I have heard their cry on account of their taskmasters. Indeed, I know their sufferings, ⁸and I have come down to deliver them from the Egyptians, and to bring them up out of that land to a good and broad land, a land flowing with milk and honey, to the country of the Canaanites, the Hittites, the Amorites, the Perizzites, the Hivites, and the Jebusites. ⁹The cry of the Israelites has now come to me; I have also seen how the Egyptians oppress them. ¹⁰So come, I will send you to Pharaoh to bring my people, the Israelites, out of Egypt.”

¹¹But Moses said to God, “Who am I that I should go to Pharaoh, and bring the Israelites out of Egypt?” ¹²He said, “I will be with you; and this shall be the sign for you that it is I who sent you: when you have brought the people out of Egypt, you shall worship God on this mountain.” ¹³But Moses said to God, “If I come to the Israelites and say to them, ‘The God of your ancestors has sent me to you,’ and they ask me, ‘What is his name?’ what shall I say to them?” ¹⁴God said to Moses, “I AM WHO I AM.” He said further, “Thus you shall say to the Israelites, ‘I AM has sent me to you.’” ¹⁵God also said to Moses, “Thus you shall say to the Israelites, ‘The Lord, the God of your ancestors, the God of Abraham, the God of Isaac, and the God of Jacob, has sent me to you’: This is my name forever, and this my title for all generations.

Psalm: Psalm 105:1-6, 23-26, 45c

¹ Give thanks to the Lord and call upon his Name; *
       make known his deeds among the peoples.
² Sing to him, sing praises to him, *
       and speak of all his marvelous works.
³ Glory in his holy Name; *
       let the hearts of those who seek the Lord rejoice.
⁴ Search for the Lord and his strength; *
       continually seek his face.
⁵ Remember the marvels he has done, *
       his wonders and the judgments of his mouth,
⁶ O offspring of Abraham his servant, *
       O children of Jacob his chosen.
²³ Israel came into Egypt, *
       and Jacob became a sojourner in the land of Ham.
²⁴ The Lord made his people exceedingly fruitful; *
       he made them stronger than their enemies;
²⁵ Whose heart he turned, so that they hated his people, *
       and dealt unjustly with his servants.
²⁶ He sent Moses his servant, *
       and Aaron whom he had chosen.
⁴⁵ Hallelujah!

Old Testament: Jeremiah 15:15-21

¹⁵O Lord, you know; remember me and visit me, and bring down retribution for me on my persecutors. In your forbearance do not take me away; know that on your account I suffer insult. ¹⁶Your words were found, and I ate them, and your words became to me a joy and the delight of my heart; for I am called by your name, O Lord, God of hosts.¹⁷I did not sit in the company of merrymakers, nor did I rejoice; under the weight of your hand I sat alone, for you had filled me with indignation. ¹⁸Why is my pain unceasing, my wound incurable, refusing to be healed? Truly, you are to me like a deceitful brook, like waters that fail. ¹⁹Therefore thus says the Lord: If you turn back, I will take you back, and you shall stand before me. If you utter what is precious, and not what is worthless, you shall serve as my mouth. It is they who will turn to you, not you who will turn to them. ²⁰And I will make you to this people a fortified wall of bronze; they will fight against you, but they shall not prevail over you, for I am with you to save you and deliver you, says the Lord. ²¹I will deliver you out of the hand of the wicked, and redeem you from the grasp of the ruthless.

Psalm: Psalm 26:1-8

¹ Give judgment for me, O Lord,
  for I have lived with integrity; *
       I have trusted in the Lord and have not faltered.
² Test me, O Lord, and try me; *
       examine my heart and my mind.
³ For your love is before my eyes; *
       I have walked faithfully with you.
⁴ I have not sat with the worthless, *
       nor do I consort with the deceitful.
⁵ I have hated the company of evildoers; *
       I will not sit down with the wicked.
⁶ I will wash my hands in innocence, O Lord, *
       that I may go in procession round your altar,
⁷ Singing aloud a song of thanksgiving *
       and recounting all your wonderful deeds.
⁸ Lord, I love the house in which you dwell *
       and the place where your glory abides.
