I'm about to send a messenger in front of you to guard you on your way and to bring you to the place that I've made ready.
References for Exodus 23:20
Pay attention to him and do as he says. Don't rebel against him. He won't forgive the things you do wrong because I am with him.
References for Exodus 23:21
But if you listen carefully to what he says and do all that I say, then I'll be an enemy to your enemies and fight those fighting you.
When my messenger goes in front of you and brings you to the Amorites, the Hittites, the Perizzites, the Canaanites, the Hivites, and the Jebusites, and I wipe them out,
don't bow down to their gods, worship them, or do what they do. Instead, you should completely destroy them and smash their sacred stone pillars to bits.
If you worship the LORD your God, the LORD will bless your bread and your water. I'll take sickness away from you,
and no woman will miscarry or be infertile in your land. I'll let you live a full, long life.
My terrifying reputation will precede you, and I'll throw all the people that you meet into a panic. I'll make all your enemies turn their backs to you.
I'll send insect swarms in front of you and drive out the Hivites, the Canaanites, and the Hittites before you.
I won't drive them out before you in a single year so the land won't be abandoned and the wild animals won't multiply around you.
I'll drive them out before you little by little, until your numbers grow and you eventually possess the land.
