Eliashib the priest; the high priest, Nehemiah 3:1, or some other priest so called, there being divers Eliashibs in or about this time, Ezra 10:6,24,27,36, though the first seems most probable, by comparing this verse with Nehemiah 13:28, and with Nehemiah 12:10,11. The oversight of the chamber, i.e. of the chambers, as appears from the following verse, and from Nehemiah 13:9, where it is called chambers, and from the nature of the thing, the high priest having the chief power over the house of God, and all the chambers belonging to it. The singular number for the plural. Allied unto Tobiah, the Ammonite, and a violent enemy to God's people. So this is noted as a great blemish to Eliashib, and as the cause of his other miscarriage, noted Nehemiah 13:5.
