"Thy (the Shepherd) anointest my head with oil;" (Psalm 23:5b, KJV)
That's CONSECRATION!
This anointing releases the aggravation, frenzy, irritability & restlessness and replaces those tendencies with quiet feeding and peaceful
contentment. Shepherds in the field smear the oily solution.
Similar to sanctification, maybe? Living for a holy purpose allowing growth in divine grace according to God's intentions through the Holy Spirit.
Such a change allows someone in need to live in comfort. (Haddon Robinson)
