'Perhaps' in the Bible

It happened, when Pharaoh had let the people go, that God didn't lead them by the way of the land of the Philistines, although that was near; for God said, "Lest perhaps the people change their minds when they see war, and they return to Egypt;"

The following day Moses said to the people, “You have committed a grave sin. Now I will go up to the Lord; perhaps I will be able to atone for your sin.”
