26 He said, “If you will diligently obey the Lord your God, and do what is right in his sight, and pay attention to his commandments, and keep all his statutes, then all the diseases that I brought on the Egyptians I will not bring on you, for I, the Lord, am your healer.”

Darby

26 And he said, If thou wilt diligently hearken to the voice of Jehovah thy God, and do what is right in his eyes, and incline thine ears to his commandments, and keep all his statutes, I will put none of the complaints upon thee that I have put upon the Egyptians; for I am Jehovah who healeth thee.

KJV

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.
