'Repent' in the Bible

And it cometh to pass in Pharaoh's sending the people away, that God hath not led them the way of the land of the Philistines, for it is near; for God said, 'Lest the people repent in their seeing war, and have turned back towards Egypt;'

why do the Egyptians speak, saying, For evil He brought them out to slay them among mountains, and to consume them from off the face of the ground? turn back from the heat of Thine anger, and repent of the evil against Thy people.
