| Clarke's Commentary on the Bible Whatsoever touches the altar shall be holy - To this our Lord refers Matthew 23:19, where he says the altar sanctifies the gift; and this may be understood as implying that whatever was laid on the altar became the Lord's property, and must be wholly devoted to sacred uses, for in no other sense could such things be sanctified by touching the altar.
