his father's brother
He was son of Josiah, brother to Jehoiakim, and uncle of Jehoiachin.
1 Chronicles 3:15 1 Chronicles 3:16 ; 2 Chronicles 36:10

The change of name was to shew Nebuchadnezzar's supremacy, and that Zedekiah was only his vassal or viceroy. The custom of changing names, we are assured by travellers, still exists in the East.
