1. Aleph.

From its commencement, dearly beloved, doth this great Psalm exhort us unto bliss, which there is no one who desireth not....And therefore this is the lesson which he teacheth, who saith, "Blessed are those that are undefiled in the way, who walk in the law of the Lord" (ver. 1). As much as to say, I know what thou wishest, thou art seeking bliss: if then thou wouldest be blessed, be undefiled. For the former all desire, the latter fear: yet without it what all wish cannot be attained. But where will any one be undefiled, save in the way? In what way, save in the law of the Lord?...
