I have heard a rumour from the LORD, and an ambassador is sent unto the heathen, saying, Gather ye together, and come against her, and rise up to the battle.
I have heard a rumour from the Lord, and an ambassador is sent unto the heathen ... rise up to the battle. Herein Jeremiah embodies in his own prophecies, and gives inspired sanction to Obadiah's words. (Obadiah 1:1-3, "We have heard a rumour from the Lord, and an ambassador is sent among the pagan ... let us rise up against her in battle").
Ambassador ... unto the heathen - a messenger from God to stir up the Chaldeans against Edom.
