Romans 9:27-29
27 And Isaiah crieth concerning Israel, If the number of the children of Israel be as the sand of the sea, it is the remnant that shall be saved:
28 for the Lord will execute [his] word upon the earth, finishing it and cutting it short.
29 And, as Isaiah hath said before, Except the Lord of Sabaoth had left us a seed, We had become as Sodom, and had been made like unto Gomorrah.
