C. F. Keil and Franz Delitzsch on 2 Kings 19:36

2Ki 19:36

This divine judgment compelled Sennacherib to retreat without delay, and to return to Nineveh, as Isaiah 28 and 32, had predicted. The heaping up of the verbs: “he decamped, departed, and returned,” expresses the hurry of the march home. בּנינוה ויּשׁב, “he sat, i.e., remained, in Nineveh,” implies not merely that Sennacherib lived for some time after his return, but also that he did not undertake any fresh expedition against Judah. On Nineveh see at Gen 10:11.
