'Slaughter' in the Bible

On the other hand, you may slaughter and eat meat as you please when the Lord your God blesses you in all your villages. Both the ritually pure and impure may eat it, whether it is a gazelle or an ibex.

If the place he chooses to locate his name is too far for you, you may slaughter any of your herd and flock he has given you just as I have stipulated; you may eat them in your villages just as you wish.

you must by all means slaughter the inhabitants of that city with the sword; annihilate with the sword everyone in it, as well as the livestock.
