'Curb' in the Bible

Keep a strong curb, however, on your youthful cravings; and strive for integrity, good faith, love, peace, in company with all who pray to the Lord with pure hearts.

For we often stumble and fall, all of us. If there is any one who never stumbles in speech, that man has reached maturity of character and is able to curb his whole nature.

Curb every passion, and be on the alert. Your great accuser, the Devil, is going about like a roaring lion to see whom he can devour.
