Here the Prophet adds a small clause to his former threats, namely, that God would so consume the whole people with slaughter, that they would be compelled to acknowledge him as Jehovah. The slain, therefore, shall fall in the midst of thee, that is, the enemy shall arise who shall cause slaughter everywhere through the midst of the land. As to the phrase, I am Jehovah, it refers to the prophecy; for the Israelites did not openly deny God, but because they had no faith in the words of the Prophet, hence God appears and confirms and establishes the authority of the prophetic teaching, when he shows that an avenger was at hand if it was despised, as we know it was despised; and this he will soon explain a little more clearly. It follows now --
The force of the words is, "When the slain shall fall in the midst of you, then at last ye shall know that I am the Lord." So in Ezekiel 6:10 where the knowledge implies a recognition of the merciful intent of Yahweh's dispensations, and therefore, a hope of restoration.
And the slain shall fall in the midst of you,.... The word for slain is in the singular number, which perhaps is put for the plural; and so the Septuagint renders it; unless it should design some principal person that should be slain; but, as King Zedekiah was not slain when the city was taken, only his sons and his princes, it seems best to understand it of the multitude that were slain in the midst of the land, not only in Jerusalem, but in all the cities of Judea; and denotes how general and public the destruction would be:
and ye shall know that I am the Lord; the only true God, and Governor of the world; who only is to be worshipped, feared, and served, and not idols.
ye shall know that I am the Lord--and not your idols, lords. Ye shall know Me as the all-powerful Punisher of sin.
