What is "jeconiah"

Jeconiah ( Yəḵānəyāh , meaning " Yah will fortify (his people)"; ; ), also known as Coniah and as Jehoiachin ( ; ), was a king of Judah who was dethroned by the King of Babylon in the 6th century BC and was taken into captivity. He was the son and successor of King Jehoiakim. Most of what is known about Jeconiah is found in the Hebrew Bible. Records of Jeconiah's existence have been found in Iraq, such as the Jehoiachin's Rations Tablets. These tablets were excavated near the Ishtar Gate in Babylon and have been dated to c. 592 BC. Written in cuneiform, they mention Jeconiah ("Ia-'-ú-kinu") and his five sons as recipients of food rations in Babylon. Comparing Babylonian records with date references found in Hebrew biblical texts, the length of Jeconiah's captivity can accurately be determined.
