32 If thou hast done foolishly in lifting up thyself, or if thou hast thought evil, lay thine hand upon thy mouth. (KJV)
32 If you have been foolish, exalting yourself, or if you have been devising evil, put your hand on your mouth. (ESV)
James said it best:
5 So also the tongue is a small member, yet it boasts of great things.
How great a forest is set ablaze by such a small fire! 6 And the tongue is a fire, a world of unrighteousness. The tongue is set among our members, staining the whole body, setting on fire the entire course of life, and set on fire by hell. 7 For every kind of beast and bird, of reptile and sea creature, can be tamed and has been tamed by mankind, 8 but no human being can tame the tongue. It is a restless evil, full of deadly poison. 9 With it we bless our Lord and Father, and with it we curse people who are made in the likeness of God. 10 From the same mouth come blessing and cursing. My brothers, these things ought not to be so. 11 Does a spring pour forth from the same opening both fresh and salt water? 12 Can a fig tree, my brothers, bear olives, or a grapevine produce figs? Neither can a salt pond yield fresh water.
13 Who is wise and understanding among you? By his good conduct let him show his works in the meekness of wisdom. 14 But if you have bitter jealousy and selfish ambition in your hearts, do not boast and be false to the truth. 15 This is not the wisdom that comes down from above, but is earthly, unspiritual, demonic. 16 For where jealousy and selfish ambition exist, there will be disorder and every vile practice. 17 But the wisdom from above is first pure, then peaceable, gentle, open to reason, full of mercy and good fruits, impartial and sincere. 18 And a harvest of righteousness is sown in peace by those who make peace.
James 3:5-18, ESV
Lord, help us to control our tongues, to rein in our pride, and to be children of humility and peace.
