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. As the hart panteth after the water brooks - The hart is not only fond of feeding near some water for the benefit of drinking, "but when he is hard hunted, and nearly spent, he will take to some river or brook, in which," says Tuberville, "he will keep as long as his breath will suffer him. Understand that when a hart is spent and sore run, his last refuge is to the water; and he will commonly descend down the streame and swimme in the very middest thereof; for he will take as good heede as he can to touch no boughes or twygges that grow upon the sides of the river, for feare lest the hounds should there take sent of him. And sometimes the hart will lye under the water, all but his very nose; and I have seene divers lye so until the hounds have been upon them, before they would rise; for they are constrayned to take the water as their last refuge." - Tuberville's Art of Venerie, chapter 40: Lond. 4th., 1611.
The above extracts will give a fine illustration of this passage. The hart feels himself almost entirely spent; he is nearly hunted down; the dogs are in full pursuit; he is parched with thirst; and in a burning heat pants after the water, and when he comes to the river, plunges in as his last refuge. Thus pursued, spent, and nearly ready to give up the ghost, the psalmist pants for God, for the living God! for him who can give life, and save from death.
