'Envoy' in the Bible

An evil messenger stumbles into trouble, but a faithful envoy brings healing.

I have heard a message from the Lord;a messenger has been sent among the nations:Assemble yourselves to come against her.Rise up for war!

The vision of Obadiah.This is what the Lord God has said about Edom:We have heard a message from the Lord;a messenger has been sent among the nations:“Rise up, and let us go to war against her.”

Or else [if he feels he is not powerful enough], while the other [king] is still a far distance away, he sends an envoy and asks for terms of peace.

But his citizens hated him, and sent an envoy after him, saying, 'We don't want this man to reign over us.'
