Arcana Coelestia # 3180
3180. 'And they called Rebekah and said to her, Are you going to go with this man? And she said, I will go' means its full consent. This becomes clear from the sense resulting from the internal sense of the words, for her reply 'I will go' to the question put to her means that she consented fully. The full consent of truth comes when truth perceives within itself the image of good, and within good the replica of itself from which it springs.
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.
