'Ruthless' in the Bible

Therefore, behold, I will bring strangers upon you,The most ruthless of the nations.And they will draw their swordsAgainst the beauty of your wisdomAnd defile your splendor.

“He and his people with him,The most ruthless of the nations,Will be brought in to destroy the land;And they will draw their swords against EgyptAnd fill the land with the slain.
