“To the chief Musician, Maschil, for the sons of Korah. As the hart panteth after the water brooks, so panteth my soul after thee, O God. Maschil: or, A Psalm giving instruction of the sons, etc panteth: Heb. brayeth”
By these similitudes of thirst and panting, he showeth his fervent desire to serve God in his Temple. As a treasure to be kept of them, which were of the number of the Levites.
