When the priests were come out - After having carried the ark into the holy of holies, before the sacred service had commenced.
And it came to pass, when the priests were come out of the holy [place]: (for all the priests [that were] present were (e) sanctified, [and] did not [then] wait by course:

The festival was so great, that not merely the course appointed to perform the service of that week, but also all the courses had sanctified themselves and co-operated in the celebration. In reference to the construction לשׁמור אין, cf. Ew. 321, b.
By course - According to David's appointment, 1Ch. 24:1-31, 25:1-22, which was only for the ordinary service, but in extraordinary solemnities, such as this, they all came together.
