12 And the men did the melachah (work) be’emunah (faithfully, with integrity); and the mufkadim (overseers) of them were Yachat and Ovadyahu, the Levi’im, of the Bnei Merari; and Zecharyah and Meshullam, of the Bnei Kehati, to give oversight; and other of the Levi’im, all that were meiven (expert) in musical instruments.

Divrey Hayamim Bais 34:12 Meaning and Commentary

2 Chronicles 34:12

And the men did that work faithfully
The labouring men, as also their inspectors, see ( 2 Kings 22:7 )

and the overseers of them were Jahath and Obadiah, the Levites, of the
sons of Merari;
the third son of Levi:

and Zechariah and Meshullam, of the sons of the Kohathites;
who had their name from Kohath, the second son of Levi:

to set it forward;
to urge and animate the men to their work, to keep them constant to it, and see that they did it well:

and other of the Levites, all that could skill of instruments of music;
these, when they were not employed in singing in the temple, attended this service, to look after the workmen at the repairs of it; and perhaps they might play, as some think, on their instruments of music, while the men were at work, that they might go on in it the more pleasantly and cheerfully.

Divrey Hayamim Bais 34:12 In-Context

10 And they entrusted it into the yad oseh hamelachah (hand of the master workmen) that had hamufkadim (oversight) of the Beis Hashem, and they paid it to the workmen that wrought in the Beis Hashem, to repair and restore HaBeis [HaMikdash];

11 Even to the charashim (craftsmen, artisans) and builders gave they it, to buy quarried stones, and timber for rafters and beams, for the buildings which the Melachim of Yehudah had destroyed.

12 And the men did the melachah (work) be’emunah (faithfully, with integrity); and the mufkadim (overseers) of them were Yachat and Ovadyahu, the Levi’im, of the Bnei Merari; and Zecharyah and Meshullam, of the Bnei Kehati, to give oversight; and other of the Levi’im, all that were meiven (expert) in musical instruments.

13 Also they were over the sabalim (bearers of burdens) and the overseers of all that wrought the work in every kind of avodah; and of the Levi’im there were soferim (scribes), shoterim (officers) and sho’arim (doorkeepers).

14 And when they brought out the kesef that was brought into the Beis Hashem, Chilkiyahu HaKohen found a Sefer Torat Hashem given through Moshe.
