John Gill Commentary 2 Kings 20:12

"At that time Berodach-baladan the son of Baladan, king of Babylon, sent letters and a present unto Hezekiah; for he had heard that Hezekiah had been sick." — 2 Kings 20:12 (ASV)

At that time Berodachbaladan,.... He is called Merodachbaladan, Isaiah 39:1 , so here in the Septuagint, Syriac, and Arabic versions; See Gill on "Isaiah 39:1"; and by Metasthenes {z} his father is called Merodach, and he Ben Merodach, who reigned twenty one years, and his father fifty two; from hence to the end of 2 Kings 20:12 the same account is given in the same words as in Isa 39:1 throughout, except in 2 Kings 20:13 , where it is, "hearkened unto them," and there, "glad of them"; heard the letter the ambassadors brought with pleasure; see the notes there. See Gill on "Isaiah 39:1" and following.
