'Slaughtered' in the Bible

Should flocks and herds be slaughtered for them, to be sufficient for them? Or should all the fish of the sea be gathered together for them, to be sufficient for them?”

‘Because the Lord could not bring this people into the land which He promised them by oath, therefore He slaughtered them in the wilderness.’

You shall give it to Eleazar the priest, and it shall be brought outside the camp and be slaughtered in his presence.
