14 And above all these things put on charity, which is the bond of perfectness.

15 And let the peace of God rule in your hearts, to the which also ye are called in one body; and be ye thankful.

16 Let the word of Christ dwell in you richly in all wisdom; teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord.

17 And whatsoever ye do in word or deed, do all in the name of the Lord Jesus, giving thanks to God and the Father by him.

Psalm 28:3
3 Draw me not away with the wicked, and with the workers of iniquity, which speak peace to their neighbours, but mischief is in their hearts.

Psalm 55:21
21 The words of his mouth were smoother than butter, but war was in his heart: his words were softer than oil, yet were they drawn swords.

John 14:27
27 Peace I leave with you, my peace I give unto you: not as the world giveth, give I unto you. Let not your heart be troubled, neither let it be afraid.
