Counter-Arguments

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

Sabbath Commandment

The verse explicitly discusses offerings and specific food restrictions related to them, not the Sabbath day itself, nor does it mention the Ten Commandments.

Sabbath as Perpetual

The verse explicitly discusses dietary restrictions related to offerings, not the Sabbath, and the phrase "statute for ever" refers to these specific dietary laws, not the Sabbath itself.

First Day of the Week

The verse prohibits eating certain foods until an offering is made on a specific day, but it does not mention or refer to the "first day of the week" in any way.

Seventh-Day Sabbath

The verse explicitly states a prohibition on eating certain foods until an offering is made, and refers to this as a "statute for ever," but it makes no mention of the seventh day, Sabbath, or a day of rest.
