'Assume' in the Bible

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."

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.

to assume the task of this service and apostleship from which Judas turned aside to go to his own place."
