Matthew Poole and continuators on Jeremiah 11:2

2 Hear ye, the words of this covenant , and speak unto the men of Judah, and to the inhabitants of Jerusalem.

Gods speaking in the plural number, not hear thou, but hear ye, makes some conjecture that this was a charge given to some other Prophets either Zephaniah (if it were in Iosiahs time, Zeph. 1.1.) or Vriah (if it were in the time of Iehojachim) The term this also manifests that the Book of the Law was before Ieremiahs time, for all conclude that the Covenant here spoken of was the Covenant of the Law of God, delivered by Moses, to which the people more then once promised obedience.
