feed - including all a shepherd’s care - “tend” (Eze 34:23; Psa 23:1; Heb 13:20; 1Pe 2:25).
carry - applicable to Messiah’s restoration of Israel, as sheep scattered in all lands, and unable to move of themselves to their own land (Psa 80:1; Jer 23:3). As Israel was “carried from the womb” (that is, in its earliest days) (Isa 63:9, Isa 63:11, Isa 63:12; Psa 77:20), so it shall be in “old age” (that is, its latter days) (Isa 46:3, Isa 46:4).
gently lead - as a thoughtful shepherd does the ewes “giving suck” (Margin) (Gen 33:13, Gen 33:14).
