The Lord responded through the prophet, instructing the messengers to relay a crucial message: they were mistaken in thinking that their captivity was solely due to the observance of uncommanded fasts. Instead, the Lord warned them, indicating that the true reason for their exile was their failure to uphold His commandments and laws. This is highlighted in the following inquiry: "If ye fast or mourn in the fifth month, as ye say, for seventy years, shall ye fast unto Me?" (Zechariah 7:5). The Lord did not ordain these fasts nor did He emphasize fasting through His prophets before and after the exile; rather, He called for righteous judgment and instructed their forefathers: "Judge righteous judgment, and do mercy and bounty to everyone to his brother" (Zechariah 7:9). Their disregard for these teachings incited His anger, resulting in their expulsion from the land. Despite His cries to them before the exile, they ignored Him; now, amidst their captivity, they cry out, yet He does not respond. For it is said, "They have given their shoulders to despise, and they have weighed down their ears, that they should not hear, and they have made their heart like adamantine" (Zechariah 7:11-12).
