⁷ 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. ⁸ And he said, O Lord Jehovah, whereby shall I know that I shall inherit it? ⁹ 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.
