Hamonah
Hamonah is the name of a city tied to Ezekiel's vision of the end of Gog, where the slain of the invading host are gathered and the land is cleansed.
The city named for the multitude
In the aftermath of Gog's defeat, Yahweh gives Gog and his host a place of burial in the valley east of the sea — "the valley of Hamon-gog" — and Israel buries them there for seven months to cleanse the land (Eze 39:11-15). At the close of that account a city takes its name from the same scene: "And Hamonah will also be the name of a city. Thus they will cleanse the land" (Eze 39:16). The name marks the place where the multitudes of Gog have been put away, and the cleansing of the land is the purpose to which both the valley and the city stand as a sign.
