'Level' in the Bible

This is the one who was mentioned by the prophet Isaiah when he said,“The voice of one shouting in the wilderness,‘Prepare the road for the Lord,Make His highways straight (level, direct)!’”

Enough for the learner to be on a level with his teacher, and for the servant to be on a level with his master. If they have called the master of the house Baal-zebul, how much more will they slander his servants?

"'These who came last have done only one hour's work, and you have put them on a level with us who have worked the whole day and have borne the scorching heat.'
