“And Obededom with their brethren, threescore and eight; Obededom also the son of Jeduthun and Hosah to be porters:”
King James Version (KJV)
16:37 He left - He appointed them their work and station there.Indeed no incense was burnt there, nor sacrifices offered, because thealtars were not there. But David's prayers were directed as incense,and the lifting up of his hands as an evening sacrifice. So early didspiritual worship take place of ceremonial.
16:39 Zadok - The chief - priest at Gibeon, where the tabernacle andaltar made by Moses still were, where also the ordinary sacrificeswere offered, and the stated worship of God was performed, as theextraordinary worship was before the ark upon great occasions, as whenGod was consulted, which was to be done before the ark and by thehigh - priest, who was Abiathar.
16:40 Which he commanded Israel - These must be kept up; becausehowever in their own nature they were inferior to prayer and praise,yet as they were types of the mediation of Christ, the observance ofthem was of mighty importance.
