Exodus 23:22-26

But if thou shalt indeed obey his voice, and do all that I speak; then I will be an enemy unto thine enemies, and an adversary unto thine adversaries.

For mine Angel shall go before thee, and bring thee in unto the Amorites, and the Hittites, and the Perizzites, and the Canaanites, the Hivites, and the Jebusites: and I will cut them off.

Thou shalt not bow down to their gods, nor serve them, nor do after their works: but thou shalt utterly overthrow them, and quite break down their images.

And ye shall serve the LORD your God, and he shall bless thy bread, and thy water; and I will take sickness away from the midst of thee.

There shall nothing cast their young, nor be barren, in thy land: the number of thy days I will fulfil.
