Proverbs 27:1-6

Do not boast about tomorrow, For you do not know what a day may bring forth. Let another praise you, and not your own mouth; A stranger, and not your own lips. A stone is heavy and the sand weighty, But the provocation of a fool is heavier than both of them. Wrath is fierce and anger is a flood, But who can stand before jealousy? Better is open rebuke Than love that is concealed. Faithful are the wounds of a friend, But deceitful are the kisses of an enemy.
