Genesis 15:8

5 and He bringeth him out without, and saith, `Look attentively, I pray thee, towards the heavens, and count the stars, if thou art able to count them;` and He saith to him, `Thus is thy seed.`

6 And he hath believed in Jehovah, and He reckoneth it to him -- righteousness.

7 And He saith unto him, `I [am] Jehovah who brought thee out from Ur of the Chaldees, to give to thee this land to possess it;`

8 and he saith, `Lord Jehovah, whereby do I know that I possess it?`

9 And He saith unto him, `Take for Me a heifer of three years, and a she-goat of three years, and a ram of three years, and a turtle-dove, and a young bird;`

10 and he taketh to him all these, and separateth them in the midst, and putteth each piece over against its fellow, but the bird he hath not divided;

11 and the ravenous birds come down upon the carcases, and Abram causeth them to turn back.
