Deuteronomy 7:15

And He said, “If you will earnestly listen to the voice of Yahweh your God, and do what is right in His sight, and give ear to His commandments, and keep all His statutes, I will put none of the diseases on you which I have put on the Egyptians; for I, Yahweh, am your healer.”

“But you shall serve Yahweh your God, and He will bless your bread and your water; and I will remove sickness from your midst.

‘If you walk in My statutes and keep My commandments so as to do them,

“Now it will be, if you diligently listen to the voice of Yahweh your God, being careful to do all His commandments which I am commanding you today, Yahweh your God will set you high above all the nations of the earth.

“Yahweh will strike you with the boils of Egypt and with tumors and with the scab and with the itch, from which you cannot be healed.

“And Yahweh your God will inflict all these curses on your enemies and on those who hate you, who persecuted you.
