Sefer Hamitzvot - Lesson 28

"And you shall write them upon the doorposts of your house and upon your gates"—Deuteronomy 6:9.

We are commanded to place mezuzahs on our doorposts.

"Write this song for yourselves"—Deuteronomy 31:19.

Every male is required to acquire a complete Torah Scroll for himself. Better yet if he can write one himself—then it is considered "as if he received it from Sinai"!

One cannot suffice with a scroll that he inherits from his father or ancestors, rather one must write or acquire one oneself.
