'Envoy' in the Bible

A wicked messenger falls into adversity,But a faithful envoy brings healing.

I have heard a message from the Lord,And an envoy is sent among the nations, saying,“Gather yourselves together and come against her,And rise up for battle!”

The vision of Obadiah.Thus says the Lord God concerning Edom—We have heard a report from the Lord,And an envoy has been sent among the nations saying,“Arise and let us go against her for battle”—
