C. F. Keil and Franz Delitzsch on Psalms 76:7-9

Psa 76:7-9

Nahum also (Psa 1:6) draws the same inference from the defeat of Sennacherib as the psalmist does in Psa 76:8. מאז אפּך (cf. Rth 2:7; Jer 44:18), from the decisive turning-point onwards, from the אז in Psa 2:5, when Thine anger breaks forth. God sent forth His judiciary word from heaven into the midst of the din of war of the hostile world: immediately (cf. on the sequence of the tenses Psa 48:6, and on Hab 3:10) it was silenced, the earth was seized with fear, and its tumult was obliged to cease, when, namely, God arose on behalf of His disquieted, suffering people, when He spoke as we read in Isa 33:10, and fulfilled the prayer offered in extreme need in Isa 33:2.
