John Gill Commentary Zechariah 1:4

"Be ye not as your fathers, unto whom the former prophets cried, saying, Thus saith Jehovah of hosts, Return ye now from your evil ways, and from your evil doings: but they did not hear, nor hearken unto me, saith Jehovah." — Zechariah 1:4 (ASV)

Do not be as your fathers Who lived before the captivity, and misused the prophets and messengers of the Lord, and despised his word, and fell into gross idolatry; the evil examples of parents and ancestors are not to be followed.

to whom the former prophets have cried: such as Hosea, Isaiah, Jeremiah, and others.

saying, thus says the Lord of hosts, Turn now from your evil ways, and [from] your evil doings; by their "evil ways" may be meant their idolatrous worship; and by their "evil doings" their immoralities; or, by both, their wicked lives and conversations, both before God and men; from which they were exhorted by the former prophets to turn, and to reform; even "now", at that present time they prophesied to them, immediately, lest destruction come upon them.

but they did not hear, nor hearken to me, says the Lord; speaking by his prophets, who were sent by him, and came and spoke in his name; so that not hearing them was not hearing him who sent them, and whom they represented.
