Albert Barnes Commentary Psalms 147:9

"He giveth to the beast his food, [And] to the young ravens which cry." — Psalms 147:9 (ASV)

He gives to the beast his food—To the wild beast; to the animals that cannot toil for it themselves, as man does. Compare (Psalms 104:21), note; (Psalms 104:27–28), notes.

To the young ravens which cry—Compare the notes at (Job 38:41). See also (Psalms 145:15).
