Taken by itself, the content of Ps 49 may seem to be less than entirely positive and constructive: it contains some practical advice and destroys some dangerous delusions, but it does not seem to offer much more with respect to the issues involved. And yet it is important to read all the wisdom literature in the context of its most fundamental principle, which is that “the fear of the Lord is the beginning of wisdom” (Prov 1:7). The wisdom teacher in Ps 49 eliminates two possible kinds of human fear: the fear of foes in times of trial (v 6) and the fear that the wealthy have some kind of advantage in the face of death (v 17). The teacher eliminates those fears, without explicitly stating a more positive message; yet the positive message is clear in the whole tradition to which he belongs, that wisdom may be found in the fear, or reverence, of the Lord. That wisdom provides the meaning and purpose of living; that wisdom provides also acceptance and calm in the face of dying.
