Like the legs of the lame that hang limp is a proverb in the mouth of fools. (Proverbs 26:7)
A proverb is a common maxim, a similitude, and a parable. The Hebrew word mashal has a wide established meaning. It comes from a root meaning "to be like." Even though common, they have great authority and life changing power. They are in every aspect part of the Word of God. In the mouth of the foolish they loose their authority because a fool is not readily believed or trusted. The only proverb that makes a fool appear wise is, Proverbs 17:28, "Even a fool is counted wise when he holds his peace; When he shuts his lips, he is considered perceptive." Therefore when we act the fool we in turn make lame the wise oracles of God. A fool on Monday should not be teaching the Word of God on Sunday. To think that a weeks worth of foolishness can be shelved for an hour on Sunday is foolishness. Therefore, "Forsake foolishness and live, and go in the way of understanding."
