And I will send an angel before thee
Not the angel before promised, ( Exodus 23:20 ) the Angel of his presence, the eternal Word and Son of God, but a created angel; and so Aben Ezra observes, he does not say the Angel that was known, that his name was in him; though even this was to be looked upon as a favour, and showed that he had not utterly cast them off:
and I will drive out the Canaanite, the Amorite, and the Hittite,
the Perizzite, the Hivite, and the Jebusite;
who were now the inhabitants of the land, and these he promises drive out, to make way for their possession of it; and that "by his hand", as the Targum of Jonathan interprets it, by the hand of the angel. Only six nations are mentioned, though there were seven; the Girgashite is omitted, but added in the Septuagint version.
