Set a watch, O LORD, before my mouth; keep watch over the door of my lips.
If any man among you seems to be religious, and bridles not his tongue, but deceives his own heart, this man's religion is vain.
[To the Chief Musician. To Jeduthun. A Psalm of David.] I said, I will take heed to my ways, that I sin not with my tongue: I will keep my mouth with a bridle, while the wicked are before me.
Trust not in a friend, put not confidence in a companion: keep the doors of your mouth from her that lies in your bosom.
For in many things we all offend. If any man offend not in word, the same is a perfect man, and able also to bridle the whole body.
Keep your tongue from evil, and your lips from speaking deceit.
Let my mouth be filled with your praise and with your honor all the day.
I was dumb with silence, I held my peace, even from good; and my sorrow was stirred.
