Wash
“Washing” in the Bible represents purification - unsurprisingly! Washing dirt from the skin symbolizes using true ideas from the Lord to remove evil desires and false ideas from our minds. This is the reason that washing was such an integral part of ritual; cleaning the body to perform physical acts of worship - something with no actual spiritual value - is symbolic of repenting our evils and falsities as part of worshiping the Lord.
Leviticus 24:5-9
5
"You shall take fine flour, and bake twelve cakes of it: two tenth parts of an ephah shall be in one cake.
6
You shall set them in two rows, six on a row, on the pure gold table before Yahweh.
7
You shall put pure frankincense on each row, that it may be to the bread for a memorial, even an offering made by fire to Yahweh.
8
Every Sabbath day he shall set it in order before Yahweh continually. It is on the behalf of the children of Israel an everlasting covenant.
9
It shall be for Aaron and his sons; and they shall eat it in a holy place: for it is most holy to him of the offerings of Yahweh made by fire by a perpetual statute."
