Numbers 35:33-34

Wycliffe Bible

³³ lest ye defoul the land of your habitation, which is defouled by the (shedding of the) blood of innocent men; and it may not be cleansed in (any) other manner, no but by the blood of him, that shedded the blood of another man.

³⁴ And so your possession shall be cleansed, for I shall dwell with you; for I am the Lord, that dwell among the sons of Israel. (And so the land, in which I live with you, shall be made clean, or purified; for I am the Lord, who liveth among the Israelites.)
