C. F. Keil and Franz Delitzsch on Psalms 113:2-3

Psa 113:1-3

The call, not limited by any addition as in Psa 134:1, or eve, after the manner of Psa 103:20., extended over the earth, is given to the whole of the true Israel that corresponds to its election by grace and is faithful to its mission; and its designation by “servants of Jahve” (Ps 69:37, cf. Ps 34:23), or even “servant of Jahve” (Psa 136:22), has come into vogue more especially through the second part of Isaiah. This Israel is called upon to praise Jahve; for the praise and celebration of His Name, i.e., of His nature, which is disclosed by means of its manifestation, is a principal element, yea, the proper ground and aim, of the service, and shall finally become that which fills all time and all space. מהלּל laudatum (est), is equivalent to ἀινετόν, laudabile (lxx, Vulgate), and this does not differ greatly from laudetur. The predictive interpretation laudabitur is opposed to the context (cf. moreover Köhler on Mal 1:11).
