Charles Ellicott Commentary Isaiah 40:11

"He will feed his flock like a shepherd, he will gather the lambs in his arm, and carry them in his bosom, [and] will gently lead those that have their young." — Isaiah 40:11 (ASV)

He shall feed his flock ... —Psalms 23 is the great embodiment of the thought in the Old Testament, as John 10 is in the New, but the thought itself is everywhere (Psalms 77:20; Psalms 80:1; Jeremiah 13:17; Jeremiah 31:10; Jeremiah 1:19; Ezekiel 34:11–16; Matthew 9:36; Matthew 18:12; Luke 15:4, and others). The tender care of the shepherd for the ewes and lambs finds a parallel in Jacob’s pleas (Genesis 33:13).
