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.

3146. 'And gave straw and fodder to the camels' means instruction in truths and goods. This is clear from the meaning of 'straw' as the truths present in the natural man, and from the meaning of 'fodder' as the goods there, dealt with above in 3114. Since these things are meant by 'straw and fodder' it therefore follows that 'giving straw and fodder' is giving instruction in truths and goods. The purpose of that freedom is this: Possessing the affection for truth and being stirred by that affection, a person may become instructed in such a way that truths are implanted deep within him - within the spiritual man or the soul - where they are joined to good, as may be seen from what has been shown regarding freedom in 2870-2893.

[2] This is the way in which faith - that is, truth which is the truth of faith made to take root; and unless it is coupled to good in the rational the truth of faith never receives any life, nor does any fruit develop from it. For everything called the fruit of faith is the fruit of that good which is the good of love and charity coming by way of truth which is the truth of faith. Unless spiritual warmth, which is the good of love, is actively present in spiritual light, which is the truth of faith, man would be like ground frozen stiff, as in wintertime, when nothing grows, let alone bears any fruit. For just as light devoid of warmth is totally unproductive, so is faith devoid of love.
