Alma 34:10

for it is expedient that there should be a great and last sacrifice; yea, not a sacrifice of man, neither of beast, neither of any manner of fowl; for it shall not be a human sacrifice; but it must be an Infinite and an Eternal sacrifice.

There must be a great and last sacrifice. It will not be a sacrifice of a person, an animal, or a bird. It will not be a human sacrifice. It must be an endless sacrifice that lasts forever.

There has to be a great and final sacrifice. Not a human sacrifice. Not an animal or a bird. It must be an infinite and eternal sacrifice.
