Deut 25:7-10
7 And if the man like not to take his [ deceased ] brother's wife, then let his brother's wife go up to the gate unto the elders, and say, My husband's brother refuseth to raise up unto his brother a name in Israel, he will not perform the duty of my husband's brother.
8 Then the elders of his city shall call him, and speak unto him: and if he stand to it, and say, I like not to take her;
9 Then shall his brother's wife come unto him in the presence of the elders, and loose his shoe from off his foot, and spit in his face, and shall answer and say, So shall it be done unto that man that will not build up his brother's house.
10 And his name shall be called in Israel, The house of him that hath his shoe loosed.
(KJV)

3 And Abram fell on his face: and God talked with him, saying,
4 As for me, behold, my covenant is with thee, and thou shalt be a father of many nations.
5 Neither shall thy name any more be called Abram [exalted father] , but thy name shall be Abraham [father of a multitude]; for a father of many nations have I made thee.
