Genesis 15:5

2 And Abram saith, `Lord Jehovah, what dost Thou give to me, and I am going childless? and an acquired son in my house is Demmesek Eliezer.`

3 And Abram saith, `Lo, to me Thou hast not given seed, and lo, a domestic doth heir me.`

4 And lo, the word of Jehovah [is] unto him, saying, `This [one] doth not heir thee; but he who cometh out from thy bowels, he doth heir thee;`

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?`
