John Gill, on Neh 13:3

“And it came to pass, when they had heard the law, that they separated every stranger from Israel.”

“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.”
