John 13:5 (CSB)

5 Next, he poured water into a basin and began to wash his disciples’ feet and to dry them with the towel tied around him.

Matthew 6:2–4 (CSB)

2 So whenever you give to the poor, don’t sound a trumpet before you, as the hypocrites do in the synagogues and on the streets, to be applauded by people. Truly I tell you, they have their reward. 3 But when you give to the poor, don’t let your left hand know what your right hand is doing, 4 so that your giving may be in secret. And your Father who sees in secret will reward you.,
