Acts 7:35, 54

“This Moses whom they rejected, saying, ‘WHO MADE YOU A RULER AND A JUDGE?’ is the very one whom God sent to be both a ruler and a deliverer, with the [protecting and helping] hand of the Angel who appeared to him in the thorn bush. [Ex 2:14]

Now when they heard this [accusation and understood its implication], they were cut to the heart, and they began grinding their teeth [in rage] at him.
