Encheirium
From BiblePortal Wikipedia
Encheirium [1]
( Ἐγχείριον ) is the napkin with which the priest wipes his hands, and which he wears at the girdle. Germanus of Constantinople describes it as above, and says that "to have a napkin at the girdle is typical of him who washed his hands and said, 'I am innocent' ( Matthew 27:24)."
