Romans 9:7

"And God said unto Abraham, Let it not be grievous in thy sight because of the lad, and because of thy bondwoman; in all that Sarah hath said unto thee, hearken unto her voice; for in Isaac shall thy seed be called."

"Of whom it was said, That in Isaac shall thy seed be called:"

"But he who was of the bondwoman was born after the flesh; but he of the freewoman was by promise."

"For we are the circumcision, which worship God in the spirit, and rejoice in Christ Jesus, and have no confidence in the flesh."

"Bring forth therefore fruits worthy of repentance, and begin not to say within yourselves, We have Abraham to our father: for I say unto you, That God is able of these stones to raise up children unto Abraham."

"And he said, Nay, father Abraham: but if one went unto them from the dead, they will repent."

"They answered him, We be Abraham's seed, and were never in bondage to any man: how sayest thou, Ye shall be made free?"
