17 And the Lord spake to Moses, and said,
18 Also thou shalt make a great vessel of brass with his foundament to wash in, and thou shalt set it betwixt the tabernacle of witnessing and the altar; and when water is put therein,
19 Aaron and his sons shall wash therein their hands and their feet,
20 when they shall enter into the tabernacle of witnessing, and when they shall nigh to the altar, that they offer therein incense to the Lord, lest peradventure they die;
21 it shall be a lawful thing everlasting to him and to his seed by successions.
