Psalm 23 (2)
in this psalm, he pictured God’s people as lowly sheep. Why? So we would learn about the Shepherd and see how tenderly He cares for us. Sheep are defenseless animals that are prone to get lost, and they need almost constant care. You can’t drive sheep, as you do cattle; they must be led. The eastern shepherds know their sheep by name and can call them and they will come (John 10:1–5). The sheep were kept, not for food but for wool, milk, and reproduction. In this psalm, David explains that if we follow the Lord and trust Him, He will meet our every need, no matter what the circumstances may be.
23:4 a dark valley The psalmist acknowledges that life will not always be characterized by green pastures and quiet waters (v. 2). He will walk through darkness or gloom (107:10; Job 10:22).
