'Former Prophets' in the Bible

Do not become like your fathers, unto whom the former prophets, proclaimed, saying, Thus, saith Yahweh of hosts, Return, I pray you, from your wicked ways, and from your wicked practices; but they heard not, nor hearkened unto me, declareth Yahweh.

Should ye not have been doing the things which Yahweh, had proclaimed, by the hand of the former prophets, while yet Jerusalem was inhabited and in peace, with her cities round about her, - and the South and the Lowland were inhabited?

and, their heart, turned they into adamant, that they might not hear the law, nor the words which Yahweh of hosts sent by his spirit, through the former prophets, - and so there came great wrath from Yahweh of hosts.
