Trust in the Lord, and do good. Notwithstanding any difficulty which the prosperity of the wicked causes thee, trust thou still in the Lord; be sure that his providence watches over thee, and endeavour still to serve him by "doing good."
So shalt thou dwell in the land, and verily thou shalt be fed; rather, dwell in the land, and feed on faithfulness (Kay); i.e. remain where thou art, and be satisfied with the thought of God's faithfulness.
Feed on this.
