Carl Friedrich Keil and Franz Delitzsch Old Testament Commentary

Finally, we have a view of the results of the judicial interposition of God. The expression made use of to describe the satisfaction which this gives to the righteous is thoroughly Old Testament and warlike in its tone (cf. Psa 68:24). David is in fact king, and perhaps no king ever remained so long quiet in the face of the most barefaced rebellion, and checked the shedding of blood, as David did at that time. If, however, blood must nevertheless flow in streams, he knows full well that it is the blood of the partisans of his deluded son; so that the men who were led the further astray in their judgment concerning him, the more inactive he remained, will at last be compelled to confess that it does really repay one to be just, and that there is really one higher than the high ones (Ecc 5:7[8]), a deity (אלהים) above the gods (אלים( sdog) who, though not forthwith, will nevertheless assuredly execute judgment in the earth. אך here, as in Job 18:21; Isa 45:14, retains its originally affirmative signification, which it has in common with אכן. אלהים is construed with the plural (Ges. 112, rem. 3), as is frequently the case, e.g., Sa2 7:23 (where, however, the chronicler, in Ch1 17:21, has altered the older text). This is not because the heathen are speaking (Baur), but in order to set the infinite majesty and omnipotence of the heavenly Judge in contrast with these puffed-up "gods."
