Commentary for Psalms 78:71

From behind the nursing ewes He brought him For he would shepherd the nursing ewes for his father, because he was merciful and would bring the kids first and feed them the upper tips of the grasses, which are tender. Then after them he would bring out the he-goats, who would eat the middle of the grasses, and afterwards, he would bring out the older ones, who would eat the roots. Said the Holy One, blessed be He, “This one is fit to shepherd My people.”
