Radak, Targum Yonasan: He brought Kodshei Atzmo (what he himself was Makdish) to Beis Hashem. The [word to which Kodshei is] Samuch is omitted. This is like "u'Schuras v'Lo mi'Yayin" (Yeshayah 51:21; the matter from which he is intoxicated, i.e. afflictions, is omitted). Also in Divrei ha'Yamim II, 15:18 it says Kodoshav. In some Seforim it is written Kodsho, but it is pronounced Kodoshav.
