'Angel' in the Bible

the angel of the LORD appeared to him in flaming fire from the center of a bush. As Moses continued to watch, amazingly the bush kept on burning, but was not consumed.

Then the angel of God, who was going in front of the camp of Israel, moved behind them. The pillar of cloud also moved from in front of them and stood behind them,

"Look, I'm sending an angel in front of you to guard you on the way and to bring you to the place I've prepared.

because my angel will go ahead of you and will bring you to the Amorites, the Hittites, the Perizzites, the Canaanites, the Hivites, and the Jebusites, and I'll annihilate them.

Now, go, and lead the people where I told you, and now my angel will go before you, but on the day when I do punish, I'll punish them for their sin."

I'll send an angel in front of you and I'll drive out the Canaanites, the Amorites, the Hittites, the Perizzites, the Hivites, and the Jebusites.
