Proverbs 30:5-6, 8-9, 18, 32

Every word of God is pure: He is a shield unto them that put their trust in him. Add thou not unto his words, Lest he reprove thee, and thou be found a liar.

Remove far from me vanity and lies: Give me neither poverty nor riches; Feed me with food convenient for me: Lest I be full, and deny thee, and say, Who is the LORD? Or lest I be poor, and steal, And take the name of my God in vain.

There be three things which are too wonderful for me, Yea, four which I know not

If thou hast done foolishly in lifting up thyself, Or if thou hast thought evil, Lay thine hand upon thy mouth.
