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 said, "O Lord God, what will you give me, for I continue childless, and the heir of my house is Eliezer of Damascus?"
3 And Abram said, "You have given me no offspring, and so a slave born in my house is to be my heir."
4 But the word of the Lord came to him, "This man shall not be your heir; no one but your very own issue shall be your heir."
5 He brought him outside and said, "Look toward heaven and count the stars, if you are able to count them." Then he said to him, "So shall your descendants be."
6 And he believed the Lord; and the Lord reckoned it to him as righteousness.
