Ezekiel 39:14-16

Young's Literal Translation

¹⁴ And men for continual employment they separate, passing on through the land, burying with those passing by those who are left on the face of the earth, to cleanse it: at the end of seven months they search.

¹⁵ And those passing by have passed through the land, and seen a bone of man, and one hath constructed near it a sign till those burying have buried it in the valley of the multitude of Gog.

¹⁶ And also the name of the city [is] The multitude; and they have cleansed the land.
