Psalms 141:5

5¶Let the righteous [thoughtfully] strike (correct) me—it is a kindness [done to encourage my spiritual maturity].

It is [the choicest anointing] oil on the head;

Let my head not refuse [to accept and acknowledge and learn from] it;

For still my prayer is against their wicked deeds. [Prov 9:8; 19:25; 25:12; Gal 6:1]
