Albert Barnes Commentary Zechariah 12:12-14

"And the land shall mourn, every family apart; the family of the house of David apart, and their wives apart; the family of the house of Nathan apart, and their wives apart; the family of the house of Levi apart, and their wives apart; the family of the Shimeites apart, and their wives apart; all the families that remain, every family apart, and their wives apart." — Zechariah 12:12-14 (ASV)

This sorrow should be universal but also individual: the whole land is to mourn, family by family. The royal family mourns—those in the direct line of its kings, and those in a branch from Nathan (a son of David and full brother of Solomon, 1 Chronicles 3:5), whose line continued in private life yet was still an ancestral line of Jesus (Luke 3:31). In the same way, the main priestly family from Levi mourns, along with a subordinate line from a grandson of Levi, “the family of Shimei” (Numbers 3:23). And all the remaining families mourn, each with their separate sorrow, each according to Joel’s call, let the bridegroom go forth of his chamber and the bride out of her closet (Joel 2:16), each denying themselves the tenderest comforts of life.

Dionysius: “The ungrateful and ungodly, daily, as far as it is in their power, crucify Christ. As Paul says, they are crucifying to themselves the Son of God afresh and putting Him to an open shame (Hebrews 6:6). And on these, Christ, out of His boundless pity, pours forth a spirit of grace and supplication, so that, touched with compunction, with grieving and tearful feeling, they look on Christ, suffering with His suffering, and bewailing their own impurities.”

Osorius: “The likeness is in the sorrow, not in its degree. Josiah had restored religion, removed a dire superstition, restrained lax morals with healthy discipline, and recalled the declining state to its former condition. In their greatest needs, light shone on them, when his unexpected death came. With that, the whole state seemed lost. So, in the death of Christ, those who loved Him, saw His divine works, and placed their whole hope of salvation in His goodness, suddenly saw the support of their life extinguished, found themselves deprived of that most sweet contact, and all hope for the future cut off. But the grief in the death of Christ was all the more bitter, as He awakened a greater longing for Himself and had brought a firmer hope of salvation.”
