Only Jonathan the son of Asahel, and Jahaziah the son
of Tikvah, were employed about the matter
To see that this affair was conducted in the manner proposed; that the magistrates of every city brought the persons that had been delinquents, in their turns, of which they gave them notice, and took the account of them as they came:
and Meshullam and Shabbethai the Levite helped them;
assisted them in this work; the other two perhaps were priests, and both these Levites; and these four were the only persons appointed over this matter, as the phrase in the preceding clause may signify; though Jarchi interprets it to a quite contrary sense, that they were the only persons that opposed and objected to it; and so Dr. Lightfoot F18 understands it, and renders it, "stood against this matter"; in which they were seconded by the two Levites, and the sense is very probable.
