Then Jacob said unto his household, and to all that were with him, Put away the foreign gods that are among you, and purify yourselves, and change your garments:
no hand shall touch him, but he shall surely be stoned, or shot through; whether it be beast or man, he shall not live: when the trumpet soundeth long, they shall come up to the mount.
And David answered the priest, and said unto him, Of a truth women have been kept from us about these three days; when I came out, the vessels of the young men were holy, though it was but a common journey; how much more then to-day shall their vessels be holy?
and said unto them, Ye are the heads of the fathers’ houses of the Levites: sanctify yourselves, both ye and your brethren, that ye may bring up the ark of Jehovah, the God of Israel, unto the place that I have prepared for it.
everything that may abide the fire, ye shall make to go through the fire, and it shall be clean; nevertheless it shall be purified with the water for impurity: and all that abideth not the fire ye shall make to go through the water.
