Zadok took a horn of oil A vessel of oil, as the Arabic translates it; which vessel was made of an ox's horn, as Bochart observes; out of the tabernacle, and anointed Solomon It rendered his unction more solemn, and his person more sacred, that he was anointed with holy oil taken out of the tabernacle: though the Jews are generally of opinion, that it was not necessary to anoint their kings with this holy oil made by Moses. So that the earth rent An hyperbolical expression, to signify the very loud noise which the people made with their shouts and their pipes.
