G1241–διαζώννυμι–diazōnnumi

rose from the table, threw off His upper garments, and took a towel and tied it round Him.

διέζωσεν diezōsen “He girded”

Then He poured water into a basin, and proceeded to wash the feet of the disciples and to wipe them with the towel which He had put round Him.

διεζωσμένος. diezōsmenos “having girded himself.”

This made the disciple whom Jesus loved say to Peter, "It is the Master." Simon Peter therefore, when he heard the words, "It is the Master," drew on his fisherman's shirt--for he had not been wearing it--put on his girdle, and sprang into the water.

διεζώσατο, diezōsato “put on”
