This is what the Lord GOD says: On that day, thoughts will arise in your mind, and you will devise an evil plan.
God puts hooks in His enemy's jaws before the trouble even comes, so His people need not be frightened. He foresees those who will attack His church and declares Himself against them, yet turns even their wrath to His praise and the glory of His own name.

Commenting on Ezekiel 38:1-13
And thou shall say,.... What came into his mind, and what he thought of; this he shall say to his privy counsellors and ministers of state; or to the generals and officers of his army; or to his confederates and allies, and even to them all, to have their opinion and approbation of it; and to encourage them to join him, and go with him...
an evil thought--as to attacking God's people in their defenseless state.
