Contemporary of Zedekiah. He was later carried captive by Nebuchadnezzar to Babylon, and there put to death (2 Kings 25:18)

Patrilineal Ancestry As per 1 Chronicles chapter 5

Seraiah the son of Tanhumeth

(Jeremiah 40:8), one of the officials who survived the defeat and exile of Judea, a Netophathite (2 Kings 25:23).

The father of Joab

Also son of Kenaz (1 Chronicles 4:13, 14). It is unlikely that this Joab is the son of Tsruiah, King David's sister, because the Seraiah mentioned in the Book of Chronicles was the brother of Othniel, the nephew of Caleb, who lived centuries earlier. 1 Chronicles 4:13, Joshua 15:17.

The grandfather of Jehu

Also father of Joshibiah and son of Asiel (1 Chronicles 4:35).

One of those who returned from exile

Seraiah is listed among those who returned from exile with Zerubbabel in Ezra 2:2 and Nehemiah 12:1. Nehemiah 12:12 names him as the head of a priestly family.

Father or ancestor of Ezra the scribe

Seraiah is named as the father of Ezra in Ezra's genealogy (Ezra 7:1). Charles Souvay, in the Catholic Encyclopedia, notes that he is often understood "in a broad sense", meaning that Seraiah, the chief priest, spoken of in 2 Kings 25:18–21 (at the time of the fall of Judah and the deportation to Babylon), was one of Ezra's ancestors.^[1] The son of Azariah, the son of Hilkiah and brother of Jeremiah.

A ruler of the temple

(Nehemiah 11:11).

An officer of King Jehoiakim

Son of Azriel (Jeremiah 36:26)

Seraiah ben Neriah

The son of Neriah. When Zedekiah made a journey to Babylon to do homage to Nebuchadnezzar, Seraiah had charge of the royal gifts to be presented on that occasion. Jeremiah took advantage of the occasion, and sent with Seraiah a word of cheer to the exiles in Babylon, and an announcement of the doom in store for that guilty city. The scroll containing this message (Jeremiah 50:1–8) Seraiah was to read to the exiles, and then, after fixing a stone to it, was to throw it into the Euphrates, uttering, as it sank, the prayer recorded in Jeremiah 51:59–64. Babylon was at this time in the height of its glory, the greatest and most powerful monarchy in the world. Scarcely seventy years elapsed when the words of the prophet were all fulfilled. Jeremiah 51:59 is rendered in the Revised Version, "Now Seraiah was chief chamberlain," instead of "was a quiet prince," as in the Authorized Version.
