Mark 12:29-31

And Jesus answered him, The first of all the commandments is, Hear, O Israel; The Lord our God is one Lord: And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment. And the second is like, namely this, Thou shalt love thy neighbour as thyself. There is none other commandment greater than these.

Psalm 37:1-4

Fret not thyself because of evildoers, neither be thou envious against the workers of iniquity. For they shall soon be cut down like the grass, and wither as the green herb. Trust in the Lord, and do good; so shalt thou dwell in the land, and verily thou shalt be fed. Delight thyself also in the Lord: and he shall give thee the desires of thine heart.
