This once - Whether we consider the greatness of the national disgrace and suffering caused by it, or its effect upon the mind of the Jews, the burning of Jerusalem by Nebuchadnezzar, followed by the captivity of the people at Babylon, stands out as the greatest manifestation of God's "hand" in all His dealings with them.

Therefore, behold, I will this once - I will not now change my purpose. They shall be visited and carried into captivity; nothing shall prevent this: and they shall know that my name is Jehovah. Since they would not receive the abundance of my mercies, they shall know what the true God can do in the way of judgment.

Therefore, behold, I will this once cause them to know,.... Or, "at this time", as the Targum; when the Gentiles shall be convinced of the idolatry they have been brought up in, and of the vanity and falsehood of their idols; they shall be made to know the true God, God in Christ, Christ himself, whom to know is life eternal, and to know the way of life and salvation by him; and all this through the ministry of the Gospel that should be brought among them, the Spirit of God accompanying it; by means of which they should come to Christ from the ends of the earth, before predicted.

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.

Therefore, behold, I will this once {l} cause them to know, I will cause them to know my hand and my might; and they shall know that my name is JEHOVAH.

(l) They will once again feel my power and mercy for their deliverance that they may learn to worship me.

16:21 Therefore - Because all the mercy I have shewed them, will not learn them to know my might, I will once for all make them to understand it, by the dreadful strokes of my vengeance. And - They shall know that my name is Jehovah; that I am not such a one as their idols, but one who have my being from myself, and give life and being to all other things, and have all might and power in my hand, and can do whatsoever I please.

The LORD: or, JEHOVAH

Margin The Lord

Or, JEHOVAH. Ps 83:18.

21. Therefore-In order that all may be turned from idols to Jehovah, He will now give awful proof of His divine power in the judgments He will inflict.

this once-If the punishments I have heretofore inflicted have not been severe enough to teach them.

my name . Lord-Jehovah (Ps 83:18): God's incommunicable name, to apply which to idols would be blasphemy. Keeping His threats and promises (Ex 6:3).

16:14-21 The restoration from the Babylonish captivity would be remembered in place of the deliverance from Egypt; it also typified spiritual redemption, and the future deliverance of the church from antichristian oppression. But none of the sins of sinners can be hidden from God, or shall be overlooked by him. He will find out and raise up instruments of his wrath, that shall destroy the Jews, by fraud like fishers, by force like hunters. The prophet, rejoicing at the hope of mercy to come, addressed the Lord as his strength and refuge. The deliverance out of captivity shall be a figure of the great salvation to be wrought by the Messiah. The nations have often known the power of Jehovah in his wrath; but they shall know him as the strength of his people, and their refuge in time of trouble.
