Leviticus 3:17

It shall be a perpetual statute for your generations throughout all your dwellings, that ye eat neither fat nor blood.
15

And the two kidneys, and the fat that is upon them, which is by the flanks, and the caul above the liver, with the kidneys, it shall he take away.

16

And the priest shall burn them upon the altar: it is the food of the offering made by fire for a sweet savour: all the fat is the Lord’s.

17

It shall be a perpetual statute for your generations throughout all your dwellings, that ye eat neither fat nor blood.

Counter-Arguments

The strongest case that this verse does not belong in this theme.

Sabbath as Perpetual

The verse explicitly states a dietary restriction ("neither fat nor blood") and declares it a "perpetual statute," but it makes no mention of the Sabbath or any related concepts. The "perpetual statute" refers to the dietary law, not the Sabbath.
