2 Chronicles 35:15

“And the singers the sons of Asaph were in their place, etc.] In the court of the priests, singing and playing on their instruments while the sacrifices were offering: according to the commandment of David, and Asaph, and Heman, and Jeduthun the king’s seer; the same with Ethan; and everyone were seers, as Jarchi interprets it, that is, the three last: and the porters waited at every gate; such of the Levites as were in, that post and office: they might not depart from their service; to let people in and out, that came for their passover lamb, and share in their other offerings: for their brethren the Levites prepared for them; because they were not at leisure to prepare for themselves.”

“And the singers . . ., were in their place--While the priests and people were so much engaged, the choir was not idle. They had to sing certain Psalms, namely, the hundred thirteenth to the hundred eighteenth inclusive, once, twice, and even a third time, during the continuance of each company of offerers. As they could not leave their posts, for the singing was resumed as every fresh company entered, the Levites prepared for them also; for the various bands relieved each other in turn, and while the general choir was doing duty, a portion of the tuneful brethren, relieved for a time, partook of the viands that were brought them.”

“They might not depart - The singers and porters remained at their posts, while other Levites sacrificed for them and brought them their share of the lambs. return to 'Top of Page'”
