 Now the LORD said to Abram, “Go from your country and your kindred and your father’s house to the land that I will show you.  And I will make of you a great nation, and I will bless you and make your name great, so that you will be a blessing.  I will bless those who bless you, and him who dishonors you I will curse, and in you all the families of the earth shall be blessed.”
Genesis 17:1–5, 10
 When Abram was ninety-nine years old the LORD appeared to Abram and said to him, “I am God Almighty; walk before me, and be blameless,  that I may make my covenant between me and you, and may multiply you greatly.”  Then Abram fell on his face. And God said to him,  “Behold, my covenant is with you, and you shall be the father of a multitude of nations.  No longer shall your name be called Abram, but your name shall be Abraham, for I have made you the father of a multitude of nations… This is my covenant, which you shall keep, between me and you and your offspring after you: Every male among you shall be circumcised.
 And 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.  Then 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.
 And he believed the LORD, and he counted it to him as righteousness.

 And he said to him, “I am the LORD who brought you out from Ur of the Chaldeans to give you this land to possess.”  But he said, “O Lord GOD, how am I to know that I shall possess it?”  He said to him, “Bring me a heifer three years old, a female goat three years old, a ram three years old, a turtledove, and a young pigeon.”  And he brought him all these, cut them in half, and laid each half over against the other. But he did not cut the birds in half.
 When the sun had gone down and it was dark, behold, a smoking fire pot and a flaming torch passed between these pieces.  On that day the LORD made a covenant with Abram…

Romans 4:4–5, 10-11
 Now to the one who works, his wages are not counted as a gift but as his due.  And to the one who does not work but believes in him who justifies the ungodly, his faith is counted as righteousness… How then was it counted to him? Was it before or after he had been circumcised? It was not after, but before he was circumcised.  He received the sign of circumcision as a seal of the righteousness that he had by faith while he was still uncircumcised. The purpose was to make him the father of all who believe without being circumcised, so that righteousness would be counted to them as well
