The more talk, the less truth; the wise measure their words. (Proverbs 10:19, MSG)
Whenever anything disagreeable happens to you, remember Christ crucified and keep silent. —St. John of the Cross
Set a guard over my mouth, Lord; keep watch over the door of my lips. (Psalm 141:3, NIV)
Keep silent. Give rest to your tongue more often than to your hands. You will never regret that you have kept silent, but you will often regret that you spoke too much.
Careful words make for a careful life; careless talk may ruin everything. (Proverbs 13:3, MSG)
A word spoken by you when your conscience is clear and your heart is full of God’s spirit is worth ten-thousand words spoken in unbelief and sin.
—Robert Murray M’Cheyne
Let the words of my mouth and the meditation of my heart be acceptable in your sight,
O Lord, my rock and my redeemer. (Psalm 19:14, ESV)
