This video, by the band 8th day, is posted to remind us of the Brit Milah, which is commanded in the portion we read this coming Shabbat, and was originally commanded to our father Avraham...
From Lech Lecha (
Beresheit/Genesis 17:10-12):
10. This is My covenant, which you shall observe between Me and between you and between your seed after you, that every male among you be circumcised.
11. And you shall circumcise the flesh of your foreskin, and it shall be as the sign of a covenant between Me and between you.
12. And at the age of
eight days, every male shall be circumcised to you throughout your generations, one that is born in the house, or one that is purchased with money, from any foreigner, who is not of your seed.
From Tazria (
Vayikra/Leviticus 12:2-3):
2. Speak to the children of Israel, saying: If a woman conceives and gives birth to a male, she shall be unclean for seven days; as [in] the days of her menstrual flow, she shall be unclean.
3. And on the
eighth day, the flesh of his foreskin shall be circumcised.
