My head with oil thou didst not anoint - Anointing the head with oil was as common among the Jews as washing the face with water is among us. See Rth 3:3; 2Sa 12:20; 2Sa 14:2; 2Ki 4:2; and Psa 23:5, where the author alludes to the Jewish manner of receiving and entertaining a guest. Thou preparest a table for me; anointest my head with oil; givest me an overflowing cup. See Mat 5:17.
