2 Kings 19:35
33 He will go back the way he came. He will not enter this city,” says the Lord. 34 “‘I will shield this city and rescue it for the sake of my reputation and because of my promise to David my servant.’” 35 That very night the angel of the Lord went out and killed 185,000 in the Assyrian camp. When they got up early the next morning, there were all the corpses. 36 So King Sennacherib of Assyria broke camp and went on his way. He went home and stayed in Nineveh. 37 One day, as he was worshiping in the temple of his god Nisroch, his sons Adrammelech and Sharezer struck him down with the sword. They escaped to the land of Ararat; his son Esarhaddon replaced him as king.
Isaiah 37:36
34 He will go back the way he came—he will not enter this city,’ says the Lord. 35 I will shield this city and rescue it for the sake of my reputation and because of my promise to David my servant.” 36 The angel of the Lord went out and killed 185,000 troops in the Assyrian camp. When they got up early the next morning, there were all the corpses! 37 So King Sennacherib of Assyria broke camp and went on his way. He went home and stayed in Nineveh. 38 One day, as he was worshiping in the temple of his god Nisroch, his sons Adrammelech and Sharezer struck him down with the sword. They ran away to the land of Ararat; his son Esarhaddon replaced him as king.
Notes and References
"... Although much scholarship has been written about the development and transmission of 2 Kings 18–20 and Isaiah 36–39, most studies fail to seriously consider scribal error as a major source of textual divergence. Instead, these studies usually argue that the differences were the result of purposeful revision or expansion by later scribes. While some of the differences in Isaiah 38–39 can certainly be attributed to the insertion of Hezekiah’s psalm, there are still some significant differences between the accounts in Isaiah and 2 Kings that cannot be attributed to redactional activity with a high degree of confidence. After excluding the differences that are a direct result of the insertion of the Psalm of Hezekiah, I count 45 major disagreements between these two accounts that are responsible for a 140-word difference. Of these 45 variants, 11 are possible cases of haplography or dittography, but 34 cannot be easily explained as having resulted from scribal errors. These latter 34, however, are almost all one- or two-word variants and are only responsible for 37% of the difference between the parallel accounts. The bulk of the difference (63%) comes from the 11 variants that could have been caused by scribal errors ..."
