'Powerful' in the Bible

sends couriers by sea,in reed vessels on the waters.Go, swift messengers,to a nation tall and smooth-skinned,to a people feared far and near,a powerful nation with a strange language,whose land is divided by rivers.

At that time a gift will be brought to Yahweh of Hosts from a people tall and smooth-skinned, a people feared far and near, a powerful nation with a strange language, whose land is divided by rivers—to Mount Zion, the place of the name of Yahweh of Hosts.

Who is this coming from Edomin crimson-stained garments from Bozrah—this One who is splendid in His apparel,rising up proudly in His great might?It is I, proclaiming vindication,powerful to save.
