Psalm 141:5 in the King James Version
Let the righteous smite me; it shall be a kindness: and let him reprove me; it shall be an excellent oil, which shall not break my head: for yet my prayer also shall be in their calamities.
Context
4 Don’t incline my heart to any evil thing, to practice deeds of wickedness with men who work iniquity. Don’t let me eat of their delicacies.
5 Let the righteous strike me, it is kindness; let him reprove me, it is like oil on the head; don’t let my head refuse it; Yet my prayer is always against evil deeds.
6 Their judges are thrown down by the sides of the rock. They will hear my words, for they are well spoken.
