Matthew 6:4 in the King James Version
That thine alms may be in secret: and thy Father which seeth in secret himself shall reward thee openly.
Context
3 But when you do merciful deeds, don’t let your left hand know what your right hand does,
4 so that your merciful deeds may be in secret, then your Father who sees in secret will reward you openly.
5 “When you pray, you shall not be as the hypocrites, for they love to stand and pray in the synagogues and in the corners of the streets, that they may be seen by men. Most certainly, I tell you, they have received their reward.
