Romans 9:7-9

Webster(i) 7 Neither because they are the seed of Abraham, are they all children: but, In Isaac shall thy seed be called. 8 That is, They who are the children of the flesh, these are not the children of God; but the children of the promise are counted for the seed. 9 For this is the word of promise, At this time will I come, and Sarah shall have a son.
