1Now the LORD had said unto Abram, Get thee out of thy country, and from thy kindred, and from thy father's house, unto a land that I will shew thee:2And I will make of thee a great nation, and I will bless thee, and make thy name great; and thou shalt be a blessing:3And I will bless them that bless thee, and curse him that curseth thee: and in thee shall all families of the earth be blessed.4So Abram departed, as the LORD had spoken unto him; and Lot went with him: and Abram was seventy and five years old when he departed out of Haran.

23And Abraham took Ishmael his son, and all that were born in his house, and all that were bought with his money, every male among the men of Abraham's house; and circumcised the flesh of their foreskin in the selfsame day, as God had said unto him.

4And Abraham circumcised his son Isaac being eight days old, as God had commanded him.

12And he said, Lay not thine hand upon the lad, neither do thou any thing unto him: for now I know that thou fearest God, seeing thou hast not withheld thy son, thine only son from me.
