Charles Ellicott Commentary Exodus 34:11

"Observe thou that which I command thee this day: behold, I drive out before thee the Amorite, and the Canaanite, and the Hittite, and the Perizzite, and the Hivite, and the Jebusite." — Exodus 34:11 (ASV)

The Amorite, and the Canaanite ... — The same six nations are specified in Exodus 3:8; Exodus 3:17, in Exodus 23:23, and also in Exodus 33:2. In Deuteronomy 7:1, and Joshua 3:10; Joshua 24:11, the Girgashites are added, and the number of the nations is made seven.
