In Matthew 6:1-4, Jesus warns against performing righteous deeds to be seen by others. Jesus specifically condemns "hypocrites" who blow trumpets in the synagogues and streets to attract attention to their charity.

The phrase "do not let your left hand know what your right hand is doing" is a command for secrecy and humility. Jesus teaches that those who seek human praise have already received their full reward, whereas those who give in secret will be rewarded by God.
