Proverbs 24:7; Proverbs 31:8-9; Proverbs 31:26
Wisdom is too high for a fool: he openeth not his mouth in the gate.
Open thy mouth for the dumb in the cause of all such as are appointed to destruction.
Open thy mouth, judge righteously, and plead the cause of the poor and needy.
She openeth her mouth with wisdom; and in her tongue is the law of kindness.
