'Slaughter' in the Bible

"But {whenever you desire} you may slaughter, and you may eat meat according to the blessing of Yahweh your God that he has given to you in all [of] your {towns}; the unclean and the clean may eat it [just] as [they would] the gazelle and as the deer.

If the place that Yahweh your God will choose to put his name there is [too] far from you, and you slaughter any of your herd and any of your flock that Yahweh has given to you [just] as I have commanded you, then you may eat whenever you desire in your {towns}.

And leaven shall not be seen with you in any of your territory for seven days, and none of the meat that you will slaughter on the evening on the first day shall remain overnight until morning.
