'Ruthless' in the Bible

therefore look! I [am] bringing strangers over you, [the most] ruthless of [the] peoples, and they will draw their swords against the beauty of your wisdom, and they will defile your splendor.

He and his people with him, [the most] ruthless of nations, [will] be brought to destroy the land. And they will draw their swords against Egypt, and they will fill the land [with] [the] slain,

And strangers cut it off, [the most] ruthless of nations, and they abandoned it. On the mountains and in all [of the] valleys its branches fell, and its branches were broken in all the river channels of the land, and all the peoples of the world went out from its shadow, and they abandoned it.

By the swords of warriors I will cause to fall your hordes [by] [the most] ruthless of [the] nations, all of them, and they will devastate the majesty of Egypt, and all of its hordes will be destroyed.
