Moshe said to Aharon: This is what G-d meant when He said I will be sanctified amongst those who are nearest to me” (Vayikra 10:3). So we read of the tragic death of Nadav and Avihu, the two older sons of Aharon.
"And it was on the eighth day" (Vayikra 9:1). While this verse is the beginning of a new parsha, the Torah clearly links it to the previous parsha in which the seven-day celebratory festivities for the dedication of the Mishkan are described. Interestingly, next week's parsha, Tazria, also begins with a reference to the eighth day. "When a women conceives and gives birth to a boy, she shall be ritually unclean for seven days...and on the eighth day the child's foreskin shall be circumcised" (12:2-3).
