The Lord’s Covenant With AbramAfter this, the word of the Lord came to Abram in a vision:“Do not be afraid, Abram.    I am your shield,[a]    your very great reward.[b]”But Abram said, “Sovereign Lord, what can you give me since I remain childless and the one who will inherit[c] my estate is Eliezer of Damascus?” And Abram said, “You have given me no children; so a servant in my household will be my heir.”Then the word of the Lord came to him: “This man will not be your heir, but a son who is your own flesh and blood will be your heir.” He took him outside and said, “Look up at the sky and count the stars—if indeed you can count them.” Then he said to him, “So shall your offspring[d] be.”Abram believed the Lord, and he credited it to him as righteousness. 

Hagar and Ishmael

Now Sarai, Abram’s wife, had borne him no children. But she had an Egyptian slave named Hagar; so she said to Abram, “The Lord has kept me from having children. Go, sleep with my slave; perhaps I can build a family through her.”

Abram agreed to what Sarai said. So after Abram had been living in Canaan ten years, Sarai his wife took her Egyptian slave Hagar and gave her to her husband to be his wife. He slept with Hagar, and she conceived.

When she knew she was pregnant, she began to despise her mistress. Then Sarai said to Abram, “You are responsible for the wrong I am suffering. I put my slave in your arms, and now that she knows she is pregnant, she despises me. May the Lord judge between you and me.”
