Ezekiel 25:17 And I will execute great vengeance upon them with furious rebukes; and they shall know that I am the LORD, when I shall lay my vengeance upon them.
He is going to execute great vengeance on them with fury. He will do this so that they will know that He is God. He will let them know that He is not to be played with. He is really God. He really makes the decisions and sin is not a little thing to Him.
