In the thirty-seventh year of King Jehoiachin's exile in Babylon, Evil-merodach ascended to the Babylonian throne. He was kind to Jehoiachin and released him from prison on March 31 of that year.
References for Jeremiah 52:31
He spoke pleasantly to Jehoiachin and gave him preferential treatment over all the other exiled kings in Babylon.
He supplied Jehoiachin with new clothes to replace his prison garb and allowed him to dine at the king's table for the rest of his life.
The Babylonian king also gave him a regular allowance to cover his living expenses until the day of his death.
