The best antidotes for fretting are trust in God and continual engagement in doing that which is of value to God and man.
Shalt thou dwell.
Literally, “dwell thou,” a command. God’s command guarantees continuance in the land; there is no need to seek security in flight.
Thou shalt be fed.
Literally, “feed thou,” or “pasture thou,” also in the imperative mood. Some prefer to translate the clause, “feed on faithfulness.” This verse offers four rules to keep the mind calm when we are perplexed over the seeming prosperity of the wicked: (a) trust in God, (b) keep busy doing good, (c) dwell calmly where God puts us, and (d) seek God’s faithfulness.
