'Slaughtered' in the Bible

Shall flocks and herds be slaughtered for them, to be sufficient for them? Shall all the fish of the sea be gathered together for them, to be sufficient for them?"

The youth and the old man lie on the ground in the streets; My virgins and my young men are fallen by the sword: You have killed them in the day of your anger; you have slaughtered, [and] not pitied.
