First Reading: Genesis 18:1-14

God appeared to Abraham by the oaks of Mamre, as Abraham sat at the entrance of his tent in the heat of the day. He looked up and saw three people standing near him. When he saw them, he ran from the tent entrance to meet them, and bowed down to the ground. He said, “My lord, if I find favor with you, do not pass by your servant. Let a little water be brought, and wash your feet, and rest yourselves under the tree. Let me bring a little bread, that you may refresh yourselves, and after that you may pass on - since you have come to your servant.”

So they said, “Do as you have said.”

And Abraham hastened into the tent to Sarah, and said, “Make ready quickly three measures of choice flour, knead it, and make cakes.” Abraham ran to the herd, and took a calf, tender and good, and gave it to the servant, who hastened to prepare it. Then he took curds and milk and the calf that he had prepared, and set it before them; and he stood by them under the tree while they ate.

They said to him, “Where is your wife Sarah?”

And he said, “There, in the tent.”

Then one said, “I will surely return to you in due season, and your wife Sarah shall have a child.” And Sarah was listening at the tent entrance behind him.

Now Abraham and Sarah were old, advanced in age; it had ceased to be with Sarah after the manner of women. So Sarah laughed to herself, saying, “After I have grown old, and my husband is old, shall I have pleasure?”

The Lord said to Abraham, “Why did Sarah laugh, and say, ‘Shall I indeed bear a child, now that I am old?’ Is anything too wonderful for the Lord?”

Gospel Reading: Mark 6:14-29 (NRSVUE)

14 King Herod heard of it, for Jesus’s[a] name had become known. Some were[b] saying, “John the baptizer has been raised from the dead, and for this reason these powers are at work in him.” 15 But others said, “It is Elijah.” And others said, “It is a prophet, like one of the prophets of old.” 16 But when Herod heard of it, he said, “John, whom I beheaded, has been raised.”

17 For Herod himself had sent men who arrested John, bound him, and put him in prison on account of Herodias, his brother Philip’s wife, because Herod had married her. 18 For John had been telling Herod, “It is not lawful for you to have your brother’s wife.” 19 And Herodias had a grudge against him and wanted to kill him. But she could not, 20 for Herod feared John, knowing that he was a righteous and holy man, and he protected him. When he heard him, he was greatly perplexed,[d] and yet he liked to listen to him. 21 But an opportunity came when Herod on his birthday gave a banquet for his courtiers and officers and for the leaders of Galilee. 22 When his daughter Herodias came in and danced, she pleased Herod and his guests, and the king said to the girl, “Ask me for whatever you wish, and I will give it.” 23 And he swore[f] to her, “Whatever you ask me, I will give you, even half of my kingdom.” 24 She went out and said to her mother, “What should I ask for?” She replied, “The head of John the baptizer.” 25 Immediately she rushed back to the king and requested, “I want you to give me at once the head of John the Baptist on a platter.” 26 The king was deeply grieved, yet out of regard for his oaths and for the guests, he did not want to refuse her. 27 Immediately the king sent a soldier of the guard with orders to bring John’s[g] head. He went and beheaded him in the prison, 28 brought his head on a platter, and gave it to the girl. Then the girl gave it to her mother. 29 When his disciples heard about it, they came and took his body and laid it in a tomb.
