The Morrow After the Sabbath
But, is it even true that shabbath should be translated as "week"?
Now, some may ask, isn't Pentecost also called the "Feast of Weeks" though?
7620 Shabuah "lit. sevened, i.e., a week." (Strong's Hebrew and Aramaic Dictionary of the Old Testament)
Shavuah is the Hebrew word that means "week." If God intended for Pentecost to be reckoned without regard to the weekly Sabbaths, He would have inspired Moses to use this word, instead of Shabbath, in Leviticus 23:15,16.
For those who contend with the Strong's lexicon definitions given above:
Search the Holy Scripture to find wherein "Shabbath" is used in reference to a week and not the weekly Sabbath itself.
Search the Holy Scripture to find where the first day of the Feast of Unleavens is ever referred to as the "Shabbath" [Leviticus 23:15 & 16 both use the definitive article (i.e., "the"--as opposed to "a") in reference to Shabbath]. What is the only other reference to "shabbath" in Leviticus 23 prior to its use in verses 15 & 16? (the answer is found in verse 3). This contextual relation thus further shows what word ("the Sabbath" as opposed to "the week") and what day ("the Sabbath" as opposed to "the first day of the Feast of Unleavens") was meant by "shabbath" in verses 15 & 16.
The Morrow After the Sabbath
"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: Even unto the morrow after the seventh Sabbath shall ye number fifty days; and ye shall offer a new meat offering unto the LORD." (Leviticus 23:15,16)
Now, those who hold to a Nisan 16th date for beginning the count, whether they reckon by actual new moons or the CRC, teach that the word translated "Sabbath" in verse 16 (shabbath--Strong's #7676) should actually be translated as "week." Such a translation is necessary for this type of Pentecost reckoning due to the fact that Sivan 6 does not always occur on the day after a weekly Sabbath (nor do Sivan 5 or 7, for that matter) as required by Leviticus 23:16. But, if shabbath should be translated "week" in verse 16, it should likewise be so translated in verse 15 regarding which day to begin the count. Such a systematic theology though damages their doctrine for it does away with Nisan 16 as a starting point (since with such a translation, the count does not need to begin on a day after a Sabbath either).
But, is it even true that shabbath should be translated as "week"?
7676 Shabbath "intermission, i.e., (spec.) the Sabbath." (Strong's Hebrew and Aramaic Dictionary of the Old Testament)
The fact is, shabbath is never rendered "week" in Scripture, nor is it ever used to refer to the first day of the Feast of Unleavens as those who hold to a Nisan 16 Elevation Sheaf Day propose.
Now, some may ask, isn't Pentecost also called the "Feast of Weeks" though?
"Seven weeks shalt thou number unto thee: begin to number the seven weeks from such time as thou beginnest to put the sickle to the corn. And thou shalt keep the Feast of Weeks unto the LORD thy God with a tribute of a freewill offering of thine hand, which thou shalt give unto the LORD thy God, according as the LORD thy God hath blessed thee." (Deuteronomy 16:9,10)
Yes, Pentecost is the Feast of Weeks, however, the word translated "weeks" in the Scripture above (as well as Exodus 34:22; Numbers 28:26; and II Chronicles 8:13) is NOT shabbath, but rather it is shabuah:
