'Clean' in the Bible

“Wash yourselves, make yourselves clean;Remove the evil of your deeds from My sight.Cease to do evil,

For all the tables are full of filthy vomit, without a single clean place.

Then they shall bring all your brethren from all the nations as a grain offering to the Lord, on horses, in chariots, in litters, on mules and on camels, to My holy mountain Jerusalem,” says the Lord, “just as the sons of Israel bring their grain offering in a clean vessel to the house of the Lord.
