'Acting' in the Bible

My people are destroyed for lack of knowledge; because you have rejected knowledge, I reject you from acting as a priest for me. And since you have forgotten the law of your God, I will also forget your children.

I know Ephraim, and Israel cannot hide from me, since you, Ephraim, have been acting like a prostitute, defiling Israel.

The days of punishment have come; the days of retribution have come; Israel knows! The prophet [is] a fool, the man of the spirit [is] acting like a madman. Because of the greatness of your sin, [your] hostility [is] great.
