Matthew 6:2-4

Young's Literal Translation

² whenever, therefore, thou mayest do kindness, thou mayest not sound a trumpet before thee as the hypocrites do, in the synagogues, and in the streets, that they may have glory from men; verily I say to you -- they have their reward!

³ `But thou, doing kindness, let not thy left hand know what thy right hand doth,

⁴ that thy kindness may be in secret, and thy Father who is seeing in secret Himself shall reward thee manifestly.
