John 13:1-5, 14-15

Now before the Passover Feast, Jesus knew that His hour had come [and it was time] for Him to leave this world and return to the Father. Having [greatly] loved His own who were in the world, He loved them [and continuously loves them with His perfect love] to the end (eternally). It was during supper, when the devil had already put [the thought of] betraying Jesus into the heart of Judas Iscariot, Simon’s son, that Jesus, knowing that the Father had put everything into His hands, and that He had come from God and was [now] returning to God, got up from supper, took off His [outer] robe, and taking a [servant’s] towel, He tied it around His waist. Then He poured water into the basin and began washing the disciples’ feet and wiping them with the towel which was tied around His waist.

So if I, the Lord and the Teacher, washed your feet, you ought to wash one another’s feet as well. For I gave you [this as] an example, so that you should do [in turn] as I did to you.
