'Kill and Eat' in the Bible

Notwithstanding thou mayest kill and eat flesh in all thy gates, whatsoever thy soul lusteth after, according to the blessing of the LORD thy God which he hath given thee: the unclean and the clean may eat thereof, as of the roebuck, and as of the hart.

And there came a voice to him, Rise, Peter; kill and eat.

And I heard also a voice saying unto me, Rise, Peter; kill and eat.
