The book of Matthew
Take heed that ye do not your alms before men, to be seen of them; otherwise ye
have no reward of your Father which is in Heaven. Therefore when thou doest
thine alms, do not sound a trumpet before thee, as the hypocrites do in the streets,
that they may have glory of men. Verily I say unto you, They have their reward.
But when thou doest alms, let not thy left hand know what thy right hand doeth:
That thine alms may be in secret: and thy Father which Seth in secret himself shall
reward thee openly.
Matthew 6:1–4
