Exodus 23:25-27

You shall serve [only] the LORD your God, and He shall bless your bread and water. I will also remove sickness from among you. No one shall suffer miscarriage or be barren in your land; I will fulfill the number of your days. I will send My terror ahead of you, and I will throw into confusion all the people among whom you come, and I will make all your enemies turn their backs to you [in flight].
