Psa 141:1-2
The very beginning of Psa 141:1-10 is more after the manner of David than really Davidic; for instead of haste thee to me, David always says, haste thee for my help, Psa 22:20; 38:23; Psa 40:14. The לך that is added to בּקראי (as in Psa 4:2) is to be explained, as in Psa 57:3 : when I call to Thee, i.e., when I call Thee, who art now far from me, to me. The general cry for help is followed in Psa 141:2 by a petition for the answering of his prayer. Luther has given an excellent rendering: Let my prayer avail to Thee as an offering of incense; the lifting up of my hands, as an evening sacrifice (Mein Gebet müsse fur dir tügen wie ein Reuchopffer, Meine Hende auffheben, wie ein Abendopffer). תּכּון is the fut. Niph. of כּוּן, and signifies properly to be set up, and to be established, or reflexive: to place and arrange or prepare one’s self, Amo 4:12; then to continue, e.g., Psa 101:7; therefore, either let it place itself, let it appear, sistat se, or better: let it stand, continue, i.e., let my prayer find acceptance, recognition with Thee קטרת, and the lifting up of my hands מנחת־ערב. Expositors say that this in both instances is the comparatio decurtata, as in Psa 11:1 and elsewhere: as an incense-offering, as an evening mincha. But the poet purposely omits the כּ of the comparison. He wishes that God may be pleased to regard his prayer as sweet-smelling smoke or as incense, just as this was added to the azcara of the meal-offering, and gave it, in its ascending perfume, the direction upward to God, and that He may be pleased to regard the lifting up of his hands (משׂאת, the construct with the reduplication given up, from משּׂאת, or even, after the form מתּנת, from משּׂאה, here not oblatio, but according to the phrase נשׂא כפּים ידים, elevatio, Jdg 20:38, Jdg 20:40, cf. Psa 28:2, and frequently) as an evening mincha, just as it was added to the evening tamı̂d according to Exo 29:38-42, and concluded the work of the service of the day.
