Exodus 15:26

15:26 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.”

Psalms 103:3

103:3 He is the one who forgives all your sins,

who heals all your diseases,

James 5:15-16

5:15 And the prayer of faith will save the one who is sick and the Lord will raise him up – and if he has committed sins, he will be forgiven. 5:16 So confess your sins to one another and pray for one another so that you may be healed. The prayer of a righteous person has great effectiveness.
