Tehillim 39:1-2

Orthodox Jewish Bible

39 (For the one directing, even to Yedutun. Mizmor Dovid). I said, I will be shomer over my ways, that I sin not with my leshon; I will be shomer over my mouth with a muzzle, while the rashah is before me.

^2 (3) I was dumb with silence, I held my peace for the sake of tov; and my distress grew severe.
