Genesis 15:7 DBY

⁵  And he led him out, and said, Look now toward the heavens, and number the stars, if thou be able to number them. And he said to him, So shall thy seed be!

⁶  And he believed Jehovah; and he reckoned it to him [as] righteousness.

⁷  And he said to him, I am Jehovah who brought thee out of Ur of the Chaldeans, to give thee this land to possess it.

⁸  And he said, Lord Jehovah, how shall I know that I shall possess 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.
