Wroth was the Lord against your fathers with wrath - o, that is, a wrath which was indeed such, whose greatness he does not further express, but leaves to their memories to supply.

He speaks of great wrath. For it indicates no slight displeasure that He allowed the Babylonians to waste all Judah and Samaria, burn the holy places and destroy Jerusalem, remove the elect Israel to a piteous slavery in a foreign land, severed from sacrifices, entering the holy court no more nor offering the thank-offering, or tithes, or first-fruits of the law, but precluded by necessity and, fear even from the duty of celebrating his prescribed and dearest festivals.

God fulfilled His threats against your fathers; beware, then, lest by disregarding His voice by me, as they did in the case of former prophets, ye suffer like them. The special object Zechariah aims at is that they should awake from their selfish negligence to obey God's command to rebuild His temple (Haggai 1:4-8).
