Parallel
Matthew 6:18
Robinson-Pierpont Byzantine Textform · Berean Standard Bible
ὅπως μὴ φανῇς τοῖς ἀνθρώποις νηστεύων, ἀλλὰ τῷ πατρί σου τῷ ἐν τῷ κρυπτῷ· καὶ ὁ πατήρ σου ὁ βλέπων ἐν τῷ κρυπτῷ 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.
