'Ambassadors' in the Bible

that sendeth ambassadors by the sea, even in vessels of papyrus upon the waters,'saying , Go, ye swift messengers, to a nation tall and smooth, to a people terrible from their beginning onward, a nation that meteth out and treadeth down, whose land the rivers divide!

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

Behold, their valiant ones cry without; the ambassadors of peace weep bitterly.

And thou wentest to the king with oil, and didst increase thy perfumes, and didst send thine ambassadors far off, and didst debase thyself even unto Sheol.
