I will make the governors of Judah like a hearth - or “cauldron” of fire large, broad, deep, and full of fire, among the wood which is prepared for burning, and like a torch of fire in a sheaf The fire could not kindle the wood or the sheaf, of itself, unless applied to it. All is of the agency of God: “I will make.”
Ribera: “He foretells the increase of the Church, which by such persecutions shall not be diminished, but shall be marvelously increased. The preachers of the Church shall raise up all the peoples round about, shall destroy all unbelief, and shall kindle the hearts of hearers with the fire of the divine word.” “On the right hand and on the left.” Ribera: “He indicates the strength and success of the preachers, whom no one can resist nor hinder,” as our Lord says, “I will give you a mouth and wisdom, which all your adversaries shall not be able to gainsay nor resist” Luke 21:15.
And Jerusalem shall again - Rather, “yet, be inhabited.” “Yet” is a sort of burden in Zechariah’s prophecies . Osorius: “They at once burned up by the flame all the defilement of vices, and kindled the minds of people with the torch of divine love; at once consumed the enemy and cast a heavenly fire into the human heart: ‘yet;’ in despite of all appearances, of all which is against her. ‘She shall yet dwell in her own place in Jerusalem;’ for, however the waves of this world chafe and lash themselves into foam against her, they break themselves, not her; as soon as they have reached their utmost height, they fall back; if they toss themselves, and, for a moment, hide her light, they fall down at all sides, and the ray shines out, steady as before; for she is ‘founded on a rock,’ against which ‘the gates of hell’ should not ‘prevail’ Matthew 16:18.
