Romans 9:6-8

EJ2000(i) 6 ¶ Not as though the word of God has been deficient. For not all the descendants of Israel are Israelites; 7 neither, because they are the seed of Abraham, are all sons, but, In Isaac shall thy seed be called. 8 That is, Those who are sons of the flesh, these are not the sons of God; but those who are sons of the promise are counted in the generation.
