Albert Barnes Commentary Zechariah 11:16

"For, lo, I will raise up a shepherd in the land, who will not visit those that are cut off, neither will seek those that are scattered, nor heal that which is broken, nor feed that which is sound; but he will eat the flesh of the fat [sheep], and will tear their hoofs in pieces." — Zechariah 11:16 (ASV)

I will raise up - God supplies the strength or wisdom which people abuse for sin. He, in His Providence, disposes the circumstances of which the ambitious avail themselves. Antichrist, whom the Jews look for, will be as much an instrument of God for perfecting the elect as the Chaldees (Habakkuk 1:6) or the Assyrians (Amos 6:14), whom God raised up for the chastisement of His former people, or the Medes against Babylon (Isaiah 13:17).

Which shall not visit them that be cut off - Zechariah uses the imagery, yet not the exact words, of Jeremiah (Jeremiah 23:1–2) and Ezekiel (Ezekiel 34:3–4). Neglect of every duty of a shepherd to his flock (to the sick, the broken, and the sound); direct injury to them, and preying upon them, make up the picture.

Which shall not visit - Or tend, “that which is cut off”: fulfilling God’s judgment, that which is to be cut off let it be cut off (Zechariah 11:9).

Neither shall seek the young one - Better, “the scattered, dispersed,” as the Good Shepherd came to seek and to save that which was lost (Luke 19:10; Matthew 18:11). Nor heal that which is broken; bound not, Ezekiel says (Ezekiel 34:4). “The broken legs of sheep are healed in no other way than those of people; rolled in wool impregnated with oil and wine, and then bound up with splints placed around it.”

Nor feed that which standeth still - Better, “the whole” (though Jonathan renders it as in the English version), as the word always means “in its good estate,” like our prayer, “that You would strengthen those who do stand.”
