Exodus 23:25-27

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. I will send my fear before thee, and will destroy all the people to whom thou shalt come, and I will make all thine enemies turn their backs unto thee.
