This video provides footage of Tahar unknowingly "cutting" himself when he covers Leviticus 23:15-16, and then explains why GMS reading that verse serves as a "self-cut". The passage presupposes a system where a sabbath comes every seventh day, and thus the passage presupposes a system which is irreconcilable with the "lunar sabbath" doctrine taught by GMS. Leviticus 23:15-16 (along with Deuteronomy 16:9) presupposes that it is possible for seven consecutive sabbaths (or weeks) to amount to 49 days. But seven consecutive sabbaths would cross out of any single month, thus the Bible presupposes that the ending of one month and the starting of another month does not break up the week. Entering a new month does not mean starting a new week.
