Exodus 24:5

Young men... which offered burnt offerings. — It is to be noted that, even subsequently to the appointment of the Levitical priesthood, the acts of slaughtering the victims and arranging the flesh upon the altar were regarded as appropriately per formed by any Israelite (Leviticus 1:5; Leviticus 1:11, &c). The sprinkling of the blood and the lighting of the fire were the special sacrificial acts reserved to the priest (Leviticus 1:5; Leviticus 1:7; Leviticus 1:11; Leviticus 1:13). At this time, before the Levitical priest hood had been instituted, the sprinkling of the blood would seem to have been the sole act reserved. Young men were employed to slay the animals as best qualified by their strength to deal with them.

Burnt offerings... peace offerings. — Burnt offerings were at once expiatory and signs of self-dedication. Peace offerings were indications of man’s gratitude for mercies received. Both were now offered together, to mark (1) Israel’s thankfulness for being taken into covenant, and (2) Israel’s determination to consecrate itself wholly to the service of God.
