Exod.15.26

And said, If thou wilt diligently hearken to the voice of the LORD thy God, and wilt do that which is right in his sight, and wilt give ear to his commandments, and keep all his statutes, I will put none of these diseases upon thee, which I have brought upon the Egyptians: for I am the LORD that healeth thee.

Exod.15.26

That's the place where GOD set up rules and procedures; that's where he started testing them. GOD said, "If you listen, listen obediently to how GOD tells you to live in his presence, obeying his commandments and keeping all his laws, then I won't strike you with all the diseases that I inflicted on the Egyptians; I am GOD your healer."

Exod.15.26

He said, "If you listen carefully to the voice of the LORD your God and do what is right in his eyes, if you pay attention to his commands and keep all his decrees, I will not bring on you any of the diseases I brought on the Egyptians, for I am the LORD, who heals you."

Exod.15.26

and said, "If you diligently heed the voice of the LORD your God and do what is right in His sight, give ear to His commandments and keep all His statutes, I will put none of the diseases on you which I have brought on the Egyptians. For I am the LORD who heals you."
