'Cruel' in the Bible

“They seize bow and spear;They are cruel and inhuman and have no mercy.Their voice sounds like the roaring sea;They ride [in formation] on horses,Arrayed as a man for battleAgainst you, O Daughter of Zion (Jerusalem)!”

‘All your lovers (allies) have forgotten you;They do not seek and long for you.For I have injured you with the wound of an enemy,With the punishment of a cruel and merciless foe,Because your guilt is greatAnd your sins are glaring and innumerable.

“They seize their bow and spear;They are cruel and have no compassion.They sound like the roaring of the sea;They ride on horses,Every man equipped like a man [ready] for the battleAgainst you, O Daughter of Babylon.
