[Note: According to Adam Clarke the yearling was taken from the sheep, or from the goats as “the שה seh means either; and either was equally proper if without blemish. The Hebrews however in general preferred the lamb to the kid.” And Scripture states that “Your lamb shall be without blemish, a male of the first year: ye shall take it out from the sheep, or from the goats: And ye shall keep it up until the fourteenth day of the same month: and the whole assembly of the congregation of Israel shall kill it in the evening (Ex. 12:5-6).]
[Note: Some conclude that Pentecost is to be held on a Monday based on the way a person counts 50 days from the “morrow after the Sabbath” (Lev. 23:15), and the key word is “from” and what it means in regard to how to count the days to Pentecost. The Hebrew word, ‘min’ (“from”), is a term that is inclusive respective to time, and so the phrase “from the morrow after the Sabbath” means to include the day of Sunday as the first day in the count, not Monday. This is speaking of the Sunday that comes after the weekly Sabbath that usually falls between the two holy convocations associated with the Festival of Unleavened Bread.]
[Note: Among some Rabbinic and Christian conclusions the phrase “between the two evenings” has come to mean a period of time from early or late afternoon until sunset on the same day, and also a period of time from the sunset beginning the 14th day to the sunset beginning the 15th day (Nissan), which leads to the conclusion that the Passover was slain in the daylight portion of the 14th day in the late afternoon and was eaten on the night of the 15th of Nissan.]
[Note: The observances noted in Leviticus 23 are called the “fixed times of the Lord” and the “sacred occasions” in the Tanakh. In the Authorized Version of the Bible we know them as seasons, holy convocations and feasts, and in this context the relative starting and ending dates of the days of unleavened bread are not given to us in Leviticus.]
