Genesis 15:4 Meaning and Commentary

Genesis 15:4

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.

Genesis 15:4 In-Context

2 But Abram answered, "Sovereign Lord, what good will your reward do me, since I have no children? My only heir is Eliezer of Damascus.
3 You have given me no children, and one of my slaves will inherit my property."
4 Then he heard the Lord speaking to him again: "This slave Eliezer will not inherit your property; your own son will be your heir."
5 The Lord took him outside and said, "Look at the sky and try to count the stars; you will have as many descendants as that."
6 Abram put his trust in the Lord, and because of this the Lord was pleased with him and accepted him.
