Proverbs 27:1-14 (ESV)
27:1 Do not boast about tomorrow,
for you do not know what a day may bring.
2 Let another praise you, and not your own mouth;
a stranger, and not your own lips.
3 A stone is heavy, and sand is weighty,
but a fool’s provocation is heavier than both.
4 Wrath is cruel, 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;
profuse are the kisses of an enemy.
7 One who is full loathes honey,
but to one who is hungry everything bitter is sweet.
8 Like a bird that strays from its nest
is a man who strays from his home.
9 Oil and perfume make the heart glad,
and the sweetness of a friend comes from his earnest counsel. 
10 Do not forsake your friend and your father’s friend,
and do not go to your brother’s house in the day of your calamity.
Better is a neighbor who is near
than a brother who is far away.
11 Be wise, my son, and make my heart glad,
that I may answer him who reproaches me.
12 The prudent sees danger and hides himself,
but the simple go on and suffer for it.
13 Take a man’s garment when he has put up security for a stranger,
and hold it in pledge when he puts up security for an adulteress. 
14 Whoever blesses his neighbor with a loud voice,
rising early in the morning,
will be counted as cursing.
