'Powerful' in the Bible

Which sends envoys by the sea,Even in papyrus vessels on the surface of the waters.Go, swift messengers, to a nation tall and smooth,To a people feared far and wide,A powerful and oppressive nationWhose land the rivers divide.

At that time a gift of homage will be brought to the Lord of hostsFrom a people tall and smooth,Even from a people feared far and wide,A powerful and oppressive nation,Whose land the rivers divide—To the place of the name of the Lord of hosts, even Mount Zion.
