This statement has been understood in various ways by commentators. Some argue that the Lord gives these sacrifices to the priest for their well-being. Others understand this verse to highlight the mediatorial responsibilities of the priesthood. The priest, in other words, serves as both the Lord’s representative to the people as well as the people’s representative to the Lord.
20 Le sacrificateur agitera ces victimes de côté et d'autre devant l'Eternel, avec le pain des prémices et avec les deux agneaux: elles seront consacrées à l'Eternel, et appartiendront au sacrificateur.
