Захарія 8:6

"Thus saith Jehovah of hosts, If it be marvellous in the eyes of the remnant of this nation in those days, will it also be marvellous in my eyes? is the saying of Jehovah of hosts." The second clause of this verse is to be taken as a question with a negative answer, גּם for הגם, as in Sa1 22:7, and the meaning is the following: If this (what is promised in Zac 8:3-5) should appear marvellous, i.e., incredible, to the people in those days when it shall arrive, it will not on that account appear marvellous to Jehovah Himself, i.e., Jehovah will for all that cause what has been promised actually to occur. This contains an assurance not only of the greatness of the salvation set before them, but also of the certainty of its realization. "The remnant of the nation," as in Hag 1:12-14.

The work of ministers is rightly to divide the word of truth and to give every one his portion. So the prophet is here instructed to do, in the further answer he gives to the case of conscience proposed about continuing the public fasts. His answer, in the foregoing chapter, is by way of reproof to those that were disobedient and would not obey the truth. But here he is ordered to change his voice, and to speak by way of encouragement to the willing and obedient. Here are two words from the Lord of hosts, and they are both good words and comfortable words. In the former of these messages (Zac 8:1) God promises that Jerusalem shall be restored, reformed, replenished (Zac 8:2-8), that the country shall be rich, and the affairs of the nation shall be successful, their reputation retrieved, and their state in all respects the reverse of what it had been for many years past (Zac 8:9-15); he then exhorts them to reform what was amiss among them, that they might be ready for these favours designed them (Zac 8:16, Zac 8:17). In the latter of these messages (Zac 8:18) he promises that their fasts should be superseded by the return of mercy (Zac 8:19), and that thereupon they should be replenished, enriched, and strengthened, by the accession of foreigners to them (Zac 8:20-23).

8:6 The Old Testament portrays God as able to do the impossible and the miraculous—nothing is too hard for the God who made the heavens and the earth (Gen 18:14; Jer 32:17, 27; see also Matt 19:26).
