Parallel
Matthew 6:18
Nestle 1904 Greek New Testament · Berean Standard Bible
ὅπως μὴ φανῇς τοῖς ἀνθρώποις νηστεύων ἀλλὰ τῷ Πατρί σου τῷ ἐν τῷ κρυφαίῳ καὶ ὁ Πατήρ σου ὁ βλέπων ἐν τῷ κρυφαίῳ ἀποδώσει σοι
so that your fasting will not be obvious to men, but only to your Father, who is unseen. And your Father, who sees what is done in secret, will reward you.
