'Wipe' in the Bible

For My angel will go before you and bring you to the land of the Amorites, Hittites, Perizzites, Canaanites, Hivites, and Jebusites, and I will wipe them out.

Why should the Egyptians say, ‘He brought them out with an evil intent to kill them in the mountains and wipe them off the face of the earth’? Turn from Your great anger and relent concerning this disaster planned for Your people.
