That you appear not unto men to fast, but unto your Father who is in secret: and your Father, who sees in secret, shall reward you openly.
All Commentaries on Matthew 6:18 Go To Matthew 6
Jerome
AD 420
But He speaks in accordance with the manner of the province of Palestine, whereit is the custom on festival days to anoint the head. What He enjoins then is, that when we are fasting we should wear the appearance of joy and gladness.
