דברי הימים ב כו:טז פירוש: רש״י

and he trespassed against the Lord, his God - Heb. וַיִּמְעַל. Here it is appropriate to say מְעִילָה (trespass), for he sinned inadvertently, similar to (Lev. 5:15): “If a person commits a trespass (תִמְעל מַעַל) and sins inadvertently.”

and he came into the Temple of the Lord for he said, “It is proper for a king to serve the King of glory.”
