16:37 David left Asaph and his colleagues there before the ark of the Lord’s covenant to serve before the ark regularly and fulfill each day’s requirements, 16:38 including Obed-Edom and sixty-eight colleagues. Obed-Edom son of Jeduthun and Hosah were gatekeepers. 16:39 Zadok the priest and his fellow priests served before the Lord’s tabernacle at the worship center in Gibeon, 16:40 regularly offering burnt sacrifices to the Lord on the altar for burnt sacrifice, morning and evening, according to what is prescribed in the law of the Lord which he charged Israel to observe. 16:41 Joining them were Heman, Jeduthun, and the rest of those chosen and designated by name to give thanks to the Lord. (For his loyal love endures!) 16:42 Heman and Jeduthun were in charge of the music, including the trumpets, cymbals, and the other musical instruments used in praising God. The sons of Jeduthun guarded the entrance.
