Why art thou cast down, O my soul? and why art thou disquieted within me? hope thou in God: for I shall yet praise him, who is the health of my countenance, and my God. Why art thou cast down - There is no reason why thou shouldst despair. God will appear and release thee and thy brother captives and soon thy sighing and sorrowing shall flee away.
Who is the health of my countenance - As a healthy state of the constitution shows itself in the appearance of the face; God will so rejoice thy heart, heal all thy spiritual maladies, that thy face shall testify the happiness that is within thee.
There is a curious gloss on the first verse of this Psalm in my old Psalter, which I cannot withhold from the reader. The author translates and paraphrases the verse thus: -
Trans. Als the Hert yernes til the welles of waters; so my saule yernes til the God.
Par - This Psalm es al of perfite men, that er brinnand in the flamme of Goddes luf, and passes in til the contemplatyf lif: and tharfore it es sungen in the office of the dede men: for than haf that, that thai yearned; that es, the syght of God. Far thi, sais he, als the Hert that has eten the nedder, gretely yernes to com til the welles of waters for to drynk and wax yong opayne: so destroyed in me vices and unclennes, my saule desyres with brinnand yernyng, to come til the God.
Aelian, Appian, Anstotle, Nicander, and Pliny, all inform us that one cause why the hart thirsts for the waters is, that they eat serpents, and that the poison of them diffused through their entrails produces a burning heat and fever, to ease and cure themselves of which they have recourse to water. Many of the fathers tell the same tale, and from them the paraphrast in the old Psalter has borrowed what is inserted above: "Like as the hart, which has eaten the adder, greatly longs to come to the fountains of water to drink, that he may grow young again." The hart is undoubtedly a cunning animal; but it would be as difficult to believe that he eats serpents as it would be to believe that he seeks for and eats the fresh water crab or cray fish, in order to cure and make him grow young again, as Eusebius, Didymus, Theodoret, Jerome, Epiphanies, Gregory Nyssen, and others of the primitive fathers gravely inform us.
