Joiada in Wikipedia
Joiada, which means "Yahu knows," is a name found from the
form "Jehoidada" in the Old Testament and used alternately in
English versions (Neh 13:28; Neh 3:6 KJV). Joiada is the
fourth high priest after the Babylonian Exile and his name is
only found in the lists of Neh 12:10-11, 22 and in Neh 13:28.
Most historians describe Joiada as the son of Eliashib, ca.
433-410 BCE. However, it is also believed that Joiada may be
the grandson of Eliashib because there is some confusion
within the chronologies of the high priests. The word "son"
may refer to a father-son relationship, but alternatively
refers to a grandson or brother.
The only information given about Joiada is that his son
married the daughter of Sanballat the Horonite for which he
was driven out of the Temple by Nehemiah (Neh 13:28). This is
interesting because the books of Ezra and Nehemiah contain
severe instructions against marrying foreign women. These
foreign marriages led to tension between the Jewish governor
and the high-priestly family.
