Albert Barnes Commentary Ezekiel 5:13

"Thus shall mine anger be accomplished, and I will cause my wrath toward them to rest, and I shall be comforted; and they shall know that I, Jehovah, have spoken in my zeal, when I have accomplished my wrath upon them." — Ezekiel 5:13 (ASV)

Comforted - In the sense of “consoling oneself” and “feeling satisfaction in punishing;” hence, to “avenge oneself.”

The fury is to “rest” upon them, abide, so as not to pass away. The “accomplishment” of the divine anger is not the “completion” in the sense of bringing it to a close, but in the sense of carrying it out to the full.
