(21) I will this once cause them to know . . .--The warning comes with all the emphasis of iteration, this once. As in a way without a parallel, once for all, they should learn that the name of the God they had rejected was Jehovah, the Eternal (Exodus 3:14), unchangeable in His righteousness. The thought is parallel to that of Ezekiel 12:15. Verse 21. - The final answer of Jehovah. There will be no further grace-time. I will this once cause them to know; rather, I will this time (comp. on Jeremiah 10:18) cause them to acknowledge. The judgment which Jeremiah has had the sad duty of announcing will prove to the blinded Jews that Jehovah alone is true God, alone can strike and heal. I will cause them to know my hand and my might; to experience the power and efficacy of his grace in conversion; quickening their dead souls, softening their hard hearts, taking away the stony heart, and giving a heart of flesh; and making them willing in the day of his power to be saved by Christ, and to serve him; to relinquish their idols, and turn to and worship the living God in spirit and in truth: though most understand this not as a promise of grace to the Gentiles, but as a threatening of punishment to the idolatrous Jews; that because of their idolatry they should once for all, or by this one and grievous calamity, captivity in Babylon, be made to know what they could not be brought to know by all the instructions and warnings of the prophets; they should now feel the weight of the Lord's hand, the lighting down of his arm with the indignation of his wrath; and so the Targum, "I will show them my vengeance and the stroke of my power.'' And they shall know that my name is the Lord; the Jehovah, the self-existent Being, the Being of beings, the everlasting and unchangeable I AM; who is able to make good his promises, or perform his threatenings; a name incommunicable to creatures, which do not belong to the idols of the Gentiles, is peculiar to the true God, who is the most High in all the earth; see Psalm 83:18. |
