Alma 34:8-10

8 And now, behold, I will ^atestify unto you of myself that these things are true. Behold, I say unto you, that I do know that Christ shall come among the children of men, to take upon him the ^btransgressions of his people, and that he shall ^catone for the sins of the world; for the Lord God hath spoken it.

  9 For it is expedient that an ^aatonement should be made; for according to the great ^bplan of the Eternal God there must be an atonement made, or else all mankind must unavoidably perish; yea, all are hardened; yea, all are ^cfallen and are lost, and must perish except it be through the atonement which it is expedient should be made.

  10 For it is expedient that there should be a great and last ^asacrifice; yea, not a ^bsacrifice of man, neither of beast, neither of any manner of fowl; for it shall not be a human sacrifice; but it must be an ^cinfinite and ^deternal ^esacrifice.
