Leviticus 23:15

And ye shall count unto you from the morrow after the sabbath, from the day that ye brought the sheaf of the wave offering; seven sabbaths shall be complete:
13

And the meat offering thereof shall be two tenth deals of fine flour mingled with oil, an offering made by fire unto the Lord for a sweet savour: and the drink offering thereof shall be of wine, the fourth part of an hin.

14

And ye shall eat neither bread, nor parched corn, nor green ears, until the selfsame day that ye have brought an offering unto your God: it shall be a statute for ever throughout your generations in all your dwellings.

15

And ye shall count unto you from the morrow after the sabbath, from the day that ye brought the sheaf of the wave offering; seven sabbaths shall be complete:

16

Even unto the morrow after the seventh sabbath shall ye number fifty days; and ye shall offer a new meat offering unto the Lord.

17

Ye shall bring out of your habitations two wave loaves of two tenth deals: they shall be of fine flour; they shall be baken with leaven; they are the firstfruits unto the Lord.

Counter-Arguments

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

Seventh-Day Sabbath

The verse mentions "sabbaths" in the plural, referring to a count of seven such periods, but does not explicitly define or reference the seventh day of the week as *the* Sabbath or a day of rest.

First Day of the Week

The verse explicitly states "from the morrow after the sabbath," which refers to the day after the Sabbath, but it does not explicitly use the phrase "first day of the week" or any direct equivalent. While "the morrow after the sabbath" could be interpreted as the first day of the week in some contexts, the verse itself does not make that explicit connection, nor does it mention the first day of the week in any other context.
