Exodus 15:25-26

25 Then he cried to Yahweh. Yahweh shown him a tree, and he threw it into the waters, and the waters were made sweet. There he made a statute and an ordinance for them, and there he tested them;  26 and he said, "If you will diligently listen to the voice of Yahweh your God, and will do that which is right in his eyes, and will pay attention 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 am Yahweh who heals you."

1 Peter 3:10-12

10 For,  "He who would love life,  And see good days,  Let him keep his tongue from evil,  And his lips from speaking deceit.

11 Let him turn away from evil, and do good.  Let him seek peace, and pursue it.

12 For the eyes of the Lord are on the righteous,  And his ears open to their prayer;  But the face of the Lord is against those who do evil."
