'Former Prophets' in the Bible

Ye shall not be as your fathers which the former prophets called to them, saying, Thus, said Jehovah of armies: Turn back now from your evil ways and your evil doings: and they heard not, and they attended not to me, says Jehovah.

Is it not the words which Jehovah called by the hand of the former prophets in Jerusalem being inhabited and in security, and its cities round about her, and inhabiting the south and the low country?

And their heart they set a diamond from hearing the instruction and the words which Jehovah of armies sent by his spirit by the hand of the former prophets: and there will be great wrath from Jehovah of armies.
