Ezekiel 39:12-14

Young's Literal Translation

¹² And the house of Israel have buried them -- in order to cleanse the land -- seven months.

¹³ Yea, all the people of the land have buried them, and it hath been to them for a name -- the day of My being honoured -- an affirmation of the Lord Jehovah.

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.
