3157. 'Now if you are going to show mercy and truth to my master' means investigation of their consent by both mental powers - will and understanding. This is clear from the meaning of 'mercy' as that which is the essence of good or love, dealt with in 3063, 3073, 3120, and from the meaning of 'truth' as that which is the essence of truth or faith, dealt with in 3121, 3122. Now since the good of love belongs properly to the will, and the truth of faith properly to the understanding, and since the words here - which speak of showing mercy and truth - are addressed to Laban and Bethuel, and so to ordinary human beings, those words mean the things which proceed from both mental powers, from both the will and the understanding. The fact that it is investigation of the consent is evident both from the words used here ('if you are going to show') and the words that follow ('tell me; and if not, tell me, and I will look to the right or to the left').

[2] In human regeneration, which is an image of the Lord's glorification, 3138, the truth of faith may indeed be learned, but it is not acknowledged, still less accepted by good, until consent flows from both mental powers - from the will and from the understanding. Consent is acknowledgement itself. Through that acknowledgement acceptance takes place, especially by the will, for there good resides. And when the truth of faith has been accepted by the will, or what amounts to the same, by good, a person is regenerate, for in his case truth is grounded in good, and faith is grounded in charity; that is, as regards life, truth is charity itself, 3121.

The spiritual meaning of washing is purification – cleaning the mind spiritually much as water cleans the body naturally. “Feet” represent our lives on the natural level – the day-to-day outward thoughts and actions that absorb so much of our time. Washing the feet, then, symbolizes purifying the natural level of our lives, applying what the Lord teaches us to our outward, ordinary actions.

Think of it this way: Are you nice to the cashier at the grocery store? Can you forgive someone who accidentally cuts you off in traffic? Do you hold the door for strangers? Such small things may be signs of good clean feet. It also became a ritual, however, with a host honoring his guests by washing their feet. The most famous example of this is in John 13, when Jesus washed his disciples’ feet at the Last Supper.
