Farthing

(1.) Matt. 10:29; Luke 12:6. Greek assarion, i.e., a small "as",
which was a Roman coin equal to a tenth of a denarius or
drachma, nearly equal to a halfpenny of our money.

(2.) Matt. 5:26; Mark 12:42 (Gr. kodrantes), the quadrant, the
fourth of an "as", equal to two lepta, mites. The lepton (mite)
was the very smallest copper coin.
