'Assume' in the Bible

So you shall appoint Aaron and his sons, and they shall observe and attend to their priesthood; but the layman (non-Levite) who approaches [the holy things] shall be put to death.”

It shall be that the firstborn whom she bears shall assume the name of his dead brother, so that his name will not be blotted out from Israel.

But David's brother Shimeah's son Jonadab reported, "Your majesty, don't assume they've killed all of the young men the king's sons only Amnon has died, since that was Absalom's intention from the day Amnon raped his sister Tamar.

Then Absalom sent spies through all the tribes of Israel who said, "When you hear the sound of the horn, you may assume that Absalom rules in Hebron."

All who hate me speak together against me. Against me they assume the {worst} for me:

He will assume his post and shepherd the people by the Lord's strength, by the sovereign authority of the Lord his God. They will live securely, for at that time he will be honored even in the distant regions of the earth.
