2 Nephi 2:7

Behold, he offereth himself a sacrifice for sin, to answer the ends of the law, unto all those which have a broken heart and a contrite spirit; and unto none else can the ends of the law be answered.

He gives himself as a payment for sin. He does this to fulfill the law for all those who have a broken heart and a humble spirit. No one else can fulfill the law.

He offers himself as a sacrifice for sin to fulfill the law’s demands—but only for those with broken hearts and humble spirits. No one else can meet what the law requires.
