the example

Just before the Passover feast, Jesus knew that his time had come
to depart from this world to the Father. Having loved his own who were in the world,
he now loved them to the very end. The evening meal was in progress,
and the devil had already put into the heart of Judas Iscariot, Simon’s son,
that he should betray Jesus.

Because Jesus knew that the Father had handed all things over to him,
and that he had come from God and was going back to God,
he got up from the meal, removed his outer clothes,
took a towel and tied it around himself.
He poured water into the washbasin and began to wash the disciples’ feet
and to dry them with the towel he had wrapped around himself.
‭‭John‬ ‭13:1-5‬ ‭(NET‬‬)
