What’s So Special About the Birthright Anyway?
A Kohen (priest) at the time of the Beis HaMikdash (Holy Temple) had the special privilege of serving HaShem by offering sacrifices on the altar. Before the “Giving of the Torah,” the first-born of every family was the one who would offer sacrifices. That’s why Yaakov wanted the birthright – he had a burning desire to serve HaShem. And Eisav? He’d trade that for a pot of soup!
However, as we shall see at the end of this Parsha, Eisav regretted this decision, for the firstborn was destined to get the special blessings from their father, Yitzchak. This made Eisav so upset that he wanted to kill Yaakov!
