Genesis 15:1-13

After these things the word of Jehovah came unto Abram in a vision, saying, Fear not, Abram: I am thy shield, and thy exceeding great reward. And Abram said, O Lord Jehovah, what wilt thou give me, seeing I go childless, and he that shall be possessor of my house is Eliezer of Damascus? And Abram said, Behold, to me thou hast given no seed: and, lo, one born in my house is mine heir. And, behold, the word of Jehovah came unto him, saying, This man shall not be thine heir; but he that shall come forth out of thine own bowels shall be thine heir. And he brought him forth abroad, and said, Look now toward heaven, and number the stars, if thou be able to number them: and he said unto him, So shall thy seed be. And he believed in Jehovah; and he reckoned it to him for righteousness. And he said unto him, I am Jehovah that brought thee out of Ur of the Chaldees, to give thee this land to inherit it. And he said, O Lord Jehovah, whereby shall I know that I shall inherit it? And he said unto him, Take me a heifer three years old, and a she-goat three years old, and a ram three years old, and a turtle-dove, and a young pigeon. And he took him all these, and divided them in the midst, and laid each half over against the other: but the birds divided he not. And the birds of prey came down upon the carcasses, and Abram drove them away. And when the sun was going down, a deep sleep fell upon Abram; and, lo, a horror of great darkness fell upon him. And he said unto Abram, Know of a surety that thy seed shall be sojourners in a land that is not theirs, and shall serve them; and they shall afflict them four hundred years
