He, through obedience, went out from his land and from his kindred and from his father's house, that by leaving a small land, a feeble kindred, and a little house he might inherit the promises of God. For He says to him:
"Depart from your land and from your kindred and from your father's house to the land that I will show you; and I will make you into a great nation and will bless you and make your name great, and you shall be blessed; and I will bless those who bless you and curse those who curse you, and in you shall all the tribes of the earth be blessed."
And again, when he had separated from Lot, God said to him: "Lift up your eyes and look from the place where you now are, to the north and the south and the east and the sea; for all the land that you see I will give to you and to your seed forever."
And again He says: "God brought Abraham out and said to him: Look up to heaven and count the stars, if you are able to number them; so shall your seed be. And Abraham believed God, and it was reckoned to him for righteousness."
Because of faith and hospitality a son was given to him in his old age, and through obedience he offered him as a sacrifice to God upon the mountain that He showed him.
