Romans 9:9
King James Version
“For this the word of promise, At this time will I come, and Sarah shall have a son.”
Context
6Not as though the word of God hath taken none effect. For they not all Israel, which are of Israel:
7Neither, because they are the seed of Abraham, all children: but, In Isaac shall thy seed be called.
8That is, They which are the children of the flesh, these not the children of God: but the children of the promise are counted for the seed.
9For this the word of promise, At this time will I come, and Sarah shall have a son.
10And not only but when Rebecca also had conceived by one, by our father Isaac;
11(For being not yet born, neither having done any good or evil, that the purpose of God according to election might stand, not of works, but of him that calleth;)
12It was said unto her, The elder shall serve the younger.
