Ezekiel 17:24

And all the trees of the field shall know,.... All the nations of the World, and the great ones, and the mighty men of the earth, shall know, own, and acknowledge, when the above things are accomplished:

that I the Lord have brought down the high tree, have exalted the low tree, have dried up the green tree, and have made the dry tree to flourish: some by the high and green tree understand Zedekiah, who was brought low; and by the "low" and "dry tree", Jeconiah, who was raised by the king of Babylon, Jeremiah 52:11; this is Jarchi's sense, and is mentioned by Kimchi: others, by the former, think Nebuchadnezzar and the Babylonish monarchy are intended, which were brought down; and, by the latter, the house of David, and kingdom of Judah, which were exalted: though rather by the one are meant the people of the Jews, once the people of God, but now cast off; and by the other the Gentiles, called by the grace of God, and received by him: though it seems best of all to interpret the "high and green tree" of the mighty kingdoms of this world, which will be put down by Christ; and the "low and dry tree" of his kingdom and interest, which shall flourish and spread abundantly, and be an everlasting kingdom; see Daniel 2:44;

I the Lord have spoken and have done [it]; because the prophecy of it is sure, and because of the certainty of the fulfilment of it, it is said to be done as soon as it was spoken of.
