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.

6304. 'And will bring you back to the land of your fathers' means to the state of both Ancient Churches. This is clear from the meaning of 'the land' as the Church, dealt with in 566, 661, 1066, 1067, 1733, 1850, 2117, 2118, 3355, 4575, 4447, 5577; and from the meaning of 'fathers' as those who belonged to the Ancient Church and the Most Ancient Church, dealt with in 6075. To the state of both Ancient Churches is said to be meant because the sons of Israel and their descendants, like members of the Ancient Churches, were to represent in specific detail the Lord's celestial and spiritual kingdom. That representation was actually established - among the Jewish nation a representation of the celestial kingdom, and among the Israelite people a representation of the spiritual kingdom. But with that generation nothing of the Church or of the Lord's kingdom could be established, only what was a mere representation, for they wished to see and acknowledge in representatives only what was external, and nothing at all internal.

[2] However, so that the overall representation might be effected, and through it some communication with heaven might exist, and through heaven with the Lord, they were restricted to externals; and at that time the Lord saw to it that communication might take place through external representation alone devoid of any internal. This was the state to which Jacob's descendants could be 'brought back'. Yet inwardly, external representatives among those descendants concealed Divine matters, in the highest sense those which had regard to the Lord's Divine Human, and in the relative sense those which had regard to the Lord's kingdom in heaven and to the Church. This state of both Ancient Churches is what is meant by the promise that God will bring them back to the land of their fathers.
