Ezekiel 21:17

“I also will smite my hands together, and I will satisfy my fury, I Yahweh have spoken it.”

In Ezekiel 21:14 it was Ezekiel who smote his hands at what was to be. Here it is Yahweh Himself. For the set purposes of God were going forward and in the light of His final purposes His true people must feel along with Him. God's anger (His righteous abhorrence of sin) at the sinfulness of His people has long been delayed but now it must be satisfied. God has spoken! It is His final word.
