'Sixteen' in the Bible

Shimei had sixteen sons and six daughters; but his brothers did not have many sons, neither did all their family multiply like the sons of Judah.

Since there were more chief men found among the descendants of Eleazar than among the descendants of Ithamar [because of Eli’s misfortunes, and Saul’s massacre of the priests at Nob], they were divided in this way: sixteen heads of fathers’ households of the descendants of Eleazar and eight of the descendants of Ithamar, corresponding to their fathers’ households.
