Genesis 15:7 WBT

⁵  And he brought him forth abroad, and said, Look now towards heaven, and tell the stars, if thou art able to number them: and he said to him, So shall thy seed be.

⁶  And he believed in the LORD; and he counted it to him for righteousness.

⁷  And he said to him, I [am] the LORD that brought thee out of Ur of the Chaldees, to give thee this land to inherit it.

⁸  And he said, Lord GOD, by what shall I know that I shall inherit it?

⁹  And he said to him, Take me a heifer of three years old, and a she-goat of three years old, and a ram of three years old, and a turtle-dove, and a young pigeon.
