The chapter begins with a warning: do not boast about tomorrow, for you do not know what a day may bring (v. 1). Let another praise you, not your own mouth (v. 2). A stone is heavy and sand is weighty, but a fool's provocation is heavier than both (v. 3). Wrath is cruel and anger overwhelming, but who can stand before jealousy? (v. 4). Better is open rebuke than hidden love, and faithful are the wounds of a friend, while the kisses of an enemy are profuse (vv. 5-6).
The following sayings deal with home and friendship. Oil and perfume make the heart glad, and the sweetness of a friend is in his earnest counsel (v. 9). Do not forsake your friend or 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 (v. 10). The prudent sees danger and hides (v. 12). A quarrelsome wife is like a continual dripping on a rainy day (vv. 15-16). Iron sharpens iron, and one man sharpens another (v. 17). Whoever tends a fig tree will eat its fruit, and whoever serves his master will be honored (v. 18). As water reflects the face, so the heart of man reflects the man (v. 19). Sheol and Abaddon are never satisfied, and neither are the eyes of man (v. 20).
The crucible is for silver and the furnace for gold, and a person is tested by the praise he receives (v. 21). Though you crush a fool in a mortar, his folly will not depart from him (v. 22). The chapter ends with advice for the shepherd: know well the condition of your flocks and give attention to your herds, for riches do not last forever, nor a crown for all generations (vv. 23-24). The lambs will provide your clothing and the goats the price of a field, and there will be goats' milk enough for you and your household (vv. 26-27).
