Neh 13:3

“And before this,.... Before the above law was read, and observed and acted upon: Eliashib the priest; whom some take to be a common priest; so Bishop Usher (a); but he seems rather to be the high priest, by comparing it with Neh 13:28, having the oversight of the chamber of the house of our God; which has led some to the notion of his being a common priest; but chamber may be put for chambers, and those for the whole house or temple, which the high priest had the greatest concern in, and oversight of: was allied to Tobiah; the servant and Ammonite, an inveterate enemy of the Jews, Neh 2:10, having married a daughter of Shecaniah, and his son a daughter of Meshullam, who were both priests, and so as it seems related to Eliashib, Neh 6:18. (a) Annal. Vet. Test. p. 200.”

“This law being understood, all strangers were separated from Israel. ערב is taken from Exo 12:38, where it denotes the mixed multitude of non-Israelitish people who followed the Israelites at their departure from Egypt. The word is here transferred to strangers of different heathen nationalities living among the Israelites. The date of the occurrence here related cannot be more precisely defined from the ההוּא בּיּום. Public readings of the law frequently took place in those days, as is obvious from Neh 8 and 9, where we learn that in the seventh month the book of the law was publicly read, not only on the first and second days, but also daily during the feast of tabernacles, and again on the day of prayer and fasting on the twenty-fourth of the month. It appears, however, from מזּה לפני, Neh 13:4, compared with Neh 13:6, that the reading Neh 13:1-3 took place in the interval between Nehemiah's first and second stay at Jerusalem. This view is not opposed by the facts mentioned Neh 13:4. and 23f. The separation of the ערב could not be carried out at once; and hence, notwithstanding repeated resolutions to sever themselves from strangers (Neh 9:2; Neh 10:31), cases to the contrary might be discovered, and make fresh separations needful.”
