Genesis 15:4-6

Then beholde, the worde of the Lord came vnto him, saying, This man shall not be thine heire, but one that shall come out of thine owne bowels, he shalbe thine heire.

Moreouer he brought him forth and said, Looke vp nowe vnto heauen, and tell ye starres, if thou be able to number them: and he said vnto him, So shall thy seede be.

And Abram beleeued the Lord, and he counted that to him for righteousnesse.
