'Clean' in the Bible

“Wash yourselves, make yourselves clean;Get your evil deeds out of My sight.Stop doing evil,

For all the tables are full of filthy vomit, so that there is no place [that is clean.]

Depart, depart, go out from there (the lands of exile),Touch no unclean thing;Go out of the midst of her (Babylon), purify yourselves,You who carry the articles of the Lord [on your journey from there].

Then they shall bring all your countrymen (children of Israel) 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.
