Proverbs 30:10-20 RSV

10 Do not slander a servant to his master, lest he curse you, and you be held guilty.
11 There are those who curse their fathers and do not bless their mothers.
12 There are those who are pure in their own eyes but are not cleansed of their filth.
13 There are those--how lofty are their eyes, how high their eyelids lift!
14 There are those whose teeth are swords, whose teeth are knives, to devour the poor from off the earth, the needy from among men.
15 The leech has two daughters; "Give, give," they cry. Three things are never satisfied; four never say, "Enough":
16 Sheol, the barren womb, the earth ever thirsty for water, and the fire which never says, "Enough."
17 The eye that mocks a father and scorns to obey a mother will be picked out by the ravens of the valley and eaten by the vultures.
18 Three things are too wonderful for me; four I do not understand:
19 the way of an eagle in the sky, the way of a serpent on a rock, the way of a ship on the high seas, and the way of a man with a maiden.
20 This is the way of an adulteress: she eats, and wipes her mouth, and says, "I have done no wrong."
