Hebrew Bible

Proverbs 27:2

1 Do not boast about tomorrow; for you do not know what a day may bring forth. 2 Let another praise you, and not your own mouth; someone else, and not your own lips. 3 A stone is heavy and sand is weighty,but vexation by a fool is more burdensome than the two of them. 4 Wrath is cruel and anger is overwhelming, but who can stand before jealousy? 5 Better is open rebuke than hidden love. 6 Faithful are the wounds of a friend, but the kisses of an enemy are excessive. 7 The one whose appetite is satisfied loathes honey, but to the hungry mouth every bitter thing is sweet.

New Testament

Matthew 6:2

1 “Be careful not to display your righteousness merely to be seen by people. Otherwise you have no reward with your Father in heaven. 2 Thus whenever you do charitable giving, do not blow a trumpet before you, as the hypocrites do in synagogues and on streets so that people will praise them. I tell you the truth, they have their reward! 3 But when you do your giving, do not let your left hand know what your right hand is doing, 4 so that your gift may be in secret. And your Father, who sees in secret, will reward you.
