Jamieson, Fausset and Brown on Joel 3:11

11. Assemble--"Hasten" [Maurer].

thither--to the valley of Jehoshaphat.

thy mighty ones--the warriors who fancy themselves "mighty ones," but who are on that very spot to be overthrown by Jehovah [Maurer]. Compare "the mighty men" (Joe 3:9). Rather, Joel speaks of God's really "mighty ones" in contrast to the self-styled "mighty men" (Joe 3:9; Psa 103:20; Is 13:3; compare Da 10:13). Auberlen remarks: One prophet supplements the other, for they all prophesied only "in part." What was obscure to one was revealed to the other; what is briefly described by one is more fully so by another. Daniel calls Antichrist a king, and dwells on his worldly conquests; John looks more to his spiritual tyranny, for which reason he adds a second beast, wearing the semblance of spirituality. Antichrist himself is described by Daniel. Isaiah (Is 29:1-24), Joel (Joe 3:1-21) and Zechariah (Zec 12:1-14:21), describe his army of heathen followers coming up against Jerusalem, but not Antichrist himself.
