Psalms 140:3-5

³Set a watch, O Lord, on my mouth, and a strong door about my lips.

⁴Incline not my heart to evil things, to employ pretexts for sins, with men who work iniquity: and let me not unite with their choice ones.

⁵The righteous shall chasten me with mercy, and reprove me: but let not the oil of the sinner anoint my head: for yet shall my prayer also be in their pleasures.
