'Ambassadors' in the Bible

that sends ambassadors by the sea, even in vessels of papyrus on the waters, saying, "Go, you swift messengers, to a nation tall and smooth, to a people awesome from their beginning onward, a nation that measures out and treads down, whose land the rivers divide!"

For their princes are at Zoan, and their ambassadors have come to Hanes.

Behold, their valiant ones cry outside; the ambassadors of peace weep bitterly.

You went to the king with oil, and did increase your perfumes, and did send your ambassadors far off, and debased yourself even to Sheol.
