John 13:4 - Coke's Commentary on the Holy Bible

He riseth from supper,— As it is here asserted that Christ rose from supper, we must allow that, in some sense, supper was begun. Probably, the antepast had been taken, which is mentioned by the Jews as preceding the paschal lamb. They tell us that it was then usual for the master of the family to wash his hands, and, if we are rightly informed, the Jews continue this custom still. By laying aside his garments, is meant his upper garments; which the Jewish priests used to pull off, when employed in bringing the victims, frankincense, and other things requisite for sacrifice.
