Charles Ellicott 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)

I will be comforted. —The word employed here is used in two different senses: either that of feeling compassion, and so repenting of one’s anger (Isaiah 49:13; Isaiah 51:3; Isaiah 51:12; Isaiah 52:9, and elsewhere), or that of consoling oneself by taking vengeance (as in Genesis 27:42, and Isaiah 1:24—in the Authorized Version, ease myself). (Compare also Ezekiel 31:16 and Ezekiel 32:31.)

The latter is evidently the meaning here; the Divine honor, wounded by the sins of the chosen people and dishonored before the nations, was to be vindicated by their punishment in the sight of all the world.
