Numbers 19:14-16

Young's Literal Translation

¹⁴ `This [is] the law, when a man dieth in a tent: every one who is coming in unto the tent, and all that [is] in the tent, is unclean seven days;

¹⁵ and every open vessel which hath no covering of thread upon it is unclean.

¹⁶ `And every one who cometh, on the face of the field, against the pierced of a sword, or against the dead, or against a bone of man, or against a grave, is unclean seven days;
