Provision for our flourishing (verse 2-3)
Phillip Keller writes in his book “A Shepherd Looks at Psalm 23”
“sheep do not lie down easily and will not unless four conditions are met. Because they are timid, they will not lie down if they are afraid. Because they are social animals, they will not lie down if there is friction among the sheep. If flies or parasites trouble them, they will not lie down. Finally, if sheep are anxious about food or hungry, they will not lie down. Rest comes because the shepherd has dealt with fear, friction, flies, and famine.”
