Genesis 15:4

WEB

Behold, the word of the Lord came to him, saying, "This man will not be your heir, but he who will come forth out of your own body will be your heir."

KJV

And, behold, the word of the LORD came unto him, saying, This shall not be thine heir; but he that shall come forth out of thine own bowels shall be thine heir.

Commentary

And behold, the word of the Lord came unto him,.... Either having disappeared, and then came a second time, or he again spoke unto him: saying, this shall not be thine heir; this Eliezer, this servant of thine, as thou hast made him, or hast intended to make him, giving up all hopes of having issue by Sarai: but he that shall come forth out of thine own bowels shall be thine heir; that is, one shall inherit all thou hast, that shall be begotten by thee; an own son of Abram's, and not a servant born in his house; one that should spring out of his own loins: the Vulgate Latin version renders it, "out of thy womb", that is, out of his wife's, which was his; the phrase designs a genuine and legitimate son of his, who would be legally his heir.
