'Former Prophets' in the Bible

Don't you be like your fathers, to whom the former prophets proclaimed, saying: Thus says Yahweh of Armies, 'Return now from your evil ways, and from your evil doings;' but they did not hear, nor listen to me, says Yahweh.

Aren't these the words which Yahweh proclaimed by the former prophets, when Jerusalem was inhabited and in prosperity, and its cities around her, and the South and the lowland were inhabited?'"

Yes, they made their hearts as hard as flint, lest they might hear the law, and the words which Yahweh of Armies had sent by his Spirit by the former prophets. Therefore great wrath came from Yahweh of Armies.
