SEV Biblia, Chapter 9:33
Y de estos había cantores, príncipes de familias de los levitas, los cuales estaban en sus cámaras libres de otros cargos ; porque de día y de noche estaban en aquella obra.
John Gill's Bible Commentary
Ver. 33. And these are the singers, chief of the fathers of the Levites , etc.] Others of them were employed in singing, and were masters of the song, and presided in that service, (see 1 Chronicles 6:31) who remaining in the chambers were free ; from all other work and service; and there they abode, even in the chambers of the temple, that they might be near to perform their work, and not be defiled, and made unfit for it: for they were employed in that work day and night ; some or other of them, either in composing or singing psalms and hymns, or teaching others how to sing them.
Matthew Henry Commentary
Genealogies. --This chapter expresses that one end of recording all thes genealogies was, to direct the Jews, when they returned out of captivity, with whom to unite, and where to reside. Here is an accoun of the good state into which the affairs of religion were put, on the return from Babylon. Every one knew his charge. Work is likely to be done well when every one knows the duty of his place, and makes business of it. God is the God of order. Thus was the temple a figur of the heavenly one, where they rest not day nor night from praisin God, Re 4:8. Blessed be His name, believers there shall, not in turn but all together, without interruption, praise him night and day: ma the Lord make each of us fit for the inheritance of the saints in light __________________________________________________________________
