THE TEMPLE SERVANTS.

They were a group of temple personnel, often transliterated "Nethinim"(lit., "the ones given"to the service). These servants are distinct from the "Netunim"of Numbers 3:9; 8:19, taken as referring to the Levites. Except for one reference in 1 Chronicles 9:2, all references to the temple servants are included in Ezra and Nehemiah.
Ezra was an Aaronic priest, a descendant of Eleazar and Phinehas. He was an scholar and expert copist and teacher of the Law, skilled in both Hebrew and Aramaic. Ezra had a genuine zeal for pure worship and prepared his heart to consult the Law of God and to do it and to teach in Israel regulation and justice. In addition to writing the books bearing his name, Ezra wrote the 2 books of Chronicles, and Jewish tradition credits him with beginning the compiling and cataloguing of the books of the Hebrew Scriptures.
Nehemiah, son of Hacaliah,  brother of Hanani, cupbearer to the Persian King Artaxerxes and, later, governor of the Jews, was the one who rebuilt Jerusalem's wall and wrote the Bible book bearing his name.
Ezra 2: 43-58; Nehemiah 7: 46-60 list 392 temple servants among the exiles who returned to Jerusalem with Zerub-Babel.
"The temple servants: the sons of Ziha, the sons of Hasu'pha, the sons of Tabba'oth, the sons of Keros, the sons of Si'aha, the sons of Padon, the sons of Leba'nah, the sons of Hag'abah, the sons of Shamlai, the sons of Hanan, the sons of Giddel, the sons of Gahar, the sons of Re-ai'ah, the sons of Rezin, the sons of Neko'da, the sons of Gazzam, the sons of Uzza, the sons of Pase'ah, the sons of Besai, the sons of Asnah, the sons of Me-u'nim, the sons of Nephi'sim, the sons of Bakbuk, the sons of Haku'pha, the sons of Harhur, the sons of Bazluth, the sons of Mehi'da, the sons of Harsha, the sons of Barkos, the sons of Sis'era, the sons of Temah, the sons of Nezi'ah, and the sons of Hati'pha."
"The sons of Solomon's servants: the sons of So'tai, the sons of Hasso'-phereth, the sons of Peru'da, the sons of Ja'alah, the sons of Darkon, the sons of Giddel, the sons of Shephati'ah, the sons of Hattil, the sons of Po'-chereth-hazzeba'im, and the sons of Ami."
"All the temple servants and the sons of Solomon's servants were 392."
A 2nd group of 220 temple servants and 38 Levites returned with Ezra (8: 16-20).
According to Ezra 8:20 the temple servants served the Levites. They were dependent upon the income of the temple, but they were not slaves (e.g., they owned property; 1 Chron.9:2). They were a group of family guilds that served priests and Levites and worked alongside cultic personnel.
Most of the personal names in the lists of Ezra and Nehemiah are Northwest Semitic, suggesting that the temple servant families originated from neighboring peoples.
Being a servant of the Lord defines a person who belongs to the Lord and seeks to do His Will. Four poems in the Book of Isaiah center around the theme of the Servant of the Lord. (Isaiah 42: 1-4 [5-9]; 49: 1-6 [7]; 50: 4-9 [10-11]; 52:13-53:12). Scattered references to the same theme occur in Isaiah 41:8-9; 42:19; 43:10; 44:1-2,21,26; 45:4; 48:20; 50:10.
