Misinterpretations often include taking the instruction literally to mean one should be entirely unaware of their own giving, leading to impractical notions of amnesia in stewardship or finances; others apply it to justify evading accountability in organized giving or church transparency, or extend it to suppress all public good works, overlooking Jesus' commands elsewhere to let light shine before others while distinguishing showy pride from humble witness.
Matthew 6:3
King James Version (1769)
3 But when thou doest alms, let not thy left hand know what thy right hand doeth:
Jesus teaches that acts of charity should be performed in complete secrecy to avoid seeking human approval and to ensure purity of motive, with the vivid imagery of the left hand not knowing what the right hand does emphasizing utmost discretion so that God, who sees in secret, will reward openly, contrasting the hypocritical public displays of the religious leaders.
