Zedekiah was the king of Judah at the time Lehi and his colony fled from Jerusalem. (1 Nephi 1:4.) A few years later when the Babylonians besieged Jerusalem, they "slew the sons of Zedekiah before his eyes." (2 Kings 25:7.) Most people have assumed all of the sons of Zedekiah were killed at that time; however, the Book of Mormon records that the sons of Zedekiah were slain "all except it were Mulek." (Helaman 8:21.)
