Exodus 13:12 - Exposition

Set apart . The expression is especially appropriate to the case of first-born animals, which would have to be separated off from the rest of the flock, or of the herd, and "put aside" for Jehovah, so as not to be mixed up and confounded with the other lambs, kids, and calves. The males shall be the Lord's. This limitation, implied in Exodus 13:2 , is here brought prominently into notice.
