“Among the Levites, there were Jozabad, Shimei, Kelaiah, which is Kelita, Pethahiah, Judah, and Eliezer. Among the singers there was only Eliashib. However, among the gatekeepers, there were Shallum, Telem, and Uri.”
Among the Levites, it was a smaller number who had married the foreign wives. There were only 6 Levites, 1 singer, and 3 gate keepers, for a total of 10, which were 6 less than the priests.
