'Clean' in the Bible

Wash yourselves, make yourself clean. Put away the evil of your doings from before my eyes. Cease to do evil.

They shall bring all your brothers out of all the nations for an offering to Yahweh, on horses, and in chariots, and in litters, and on mules, and on dromedaries, to my holy mountain Jerusalem, says Yahweh, as the children of Israel bring their offering in a clean vessel into the house of Yahweh.
