Trust in the Lord, and do good; so you will live in the land, and enjoy security. (Psalm 37: 3)

We should bring to living an attitude of trust - batach - confidence, boldness, even a bit of carelessness. We should trust in the ultimate reality of God.

We should bring to living an ability to do - 'asah - to act, to make, to create, to produce what has value. We should do what is excellent, pleasant, and happy.

I read the Hebrew of the second phrase differently than the translator above: put down roots and feed on faithfulness.

Dwell in the land. Stop wandering. Wherever you are make friends, tend the flock, graze on the grass that is there. Be steady and keep faith.

Trust in the Lord and do good; put down roots and feed on faithfulness.
