Numbers 19:13-16

¹³Every one that touches the carcase of the person of a man, if he should have died, and the other not have been purified, has defiled the tabernacle of the Lord: that soul shall be cut off from Israel, because the water of sprinkling has not been sprinkled upon him; he is unclean; his uncleanness is yet upon him.

¹⁴And this is the law; if a man die in a house, every one that goes into the house, and all things in the house, shall be unclean seven days.

¹⁵And every open vessel which has not a covering bound upon it, shall be unclean.

¹⁶And every one who shall touch a man slain by violence, or a corpse, or human bone, or sepulchre, shall be unclean seven days.
