Exodus 29:7 - Matthew Poole's English Annotations on the Holy Bible

Which signified the gifts and graces of the Holy Ghost, wherewith Christ; as, and the priests ought to be, replenished. See Isaiah 61:1 1 John 2:27. But here ariseth a difficulty; for this anointing is sometimes spoken of as peculiar to the high priest, as Leviticus 21:10, sometimes as common to all the priests, Exodus 30:30, Exodus 40:14,15, which may be thus reconciled: the oil, was sprinkled upon all the priests, and their right ears, thumbs, and toes, and their garments, Exodus 29:20,21 Le 8:30, but it was poured out upon the head only of the high priest, Psalms 133:2, who herein was a type of Christ, who was anointed above his fellows, Psalms 45:7 Hebrews 1:9.
