Upon the burnt sacrifice; either,
1. Upon the remainders of it, which yet were burning; or rather,
2. After it; for the daily burnt-offering was first to be offered, both as more eminently respecting God's honour, which ought to be preferred before all things; and as the most solemn and stated sacrifice, which should take place of all voluntary and occasional oblation, and as a sacrifice of a higher nature and use, being for expiation and atonement, without which no peace could be obtained, nor peace-offering offered with acceptance.
