ἐκκλάω

Romans 11:17 ἐξεκλάσθησαν, were broken off,

Now if some branches have been broken off, and you, a wild olive shoot, have been grafted in among the others to share in the nourishment of the olive root,

Romans 11:19 ἐξεκλάσθησαν Were broken off

You will say then, “Branches were broken off so that I could be grafted in.”

Romans 11:20 ἐξεκλάσθησαν, they were broken off,

That is correct: They were broken off because of unbelief, but you stand by faith. Do not be arrogant, but be afraid.
