Romans 11:21 ASV

¹⁹  Thou wilt say then, Branches were broken off, that I might be grafted in.

²⁰  Well; by their unbelief they were broken off, and thou standest by thy faith. Be not highminded, but fear:

²¹  for if God spared not the natural branches, neither will he spare thee.

²²  Behold then the goodness and severity of God: toward them that fell, severity; but toward thee, God's goodness, if thou continue in his goodness: otherwise thou also shalt be cut off.

²³  And they also, if they continue not in their unbelief, shall be grafted in: for God is able to graft them in again.
