'Former Prophets' in the Bible

Be ye not as your fathers, unto whom the former prophets cried, saying, Thus saith Jehovah of hosts: Turn ye now from your evil ways, and from your evil doings; but they did not hearken nor attend unto me, saith Jehovah.

Are not these the words that Jehovah cried by the former prophets, when Jerusalem was inhabited and at peace, and her cities round about her, when the south and the lowland were inhabited?

And they made their heart as an adamant, that they should not hear the law, and the words that Jehovah of hosts sent by his Spirit by the hand of the former prophets: therefore was there great wrath from Jehovah of hosts.
