Charles H. Spurgeon on Psalms 23:5

"Thou anointest my head with oil." Anointing the head with oil is a great refreshment. There are three qualities of oil —lævor, nitor, odor, a smoothness to the touch, brightness to the sight, fragrancy to the smell, and so, gratifying the senses, it must needs cause delight to those anointed with it. To this Solomon alludes when persuading to a cheerful life, he saith, "Let thy head lack no ointment." How fully doth this represent the Spirit's unction which alone rejoices and exhilarates the soul! It is called the "oil of gladness," and the "joy of the Holy Ghost." Nathanael Hardy.
