Charles Ellicott Commentary Jeremiah 49:14

"I have heard tidings from Jehovah, and an ambassador is sent among the nations, [saying], Gather yourselves together, and come against her, and rise up to the battle." — Jeremiah 49:14 (ASV)

I have heard a rumour from the Lord ... —The thought is that of Jehovah, as the great King, sending forth His herald or envoy to call the nations to the attack on Edom. (Compare Jeremiah 46:3-4.)
