Jamieson, Fausset and Brown on Daniel 4:36

36. An inscription in the East India Company's Museum is read as describing the period of Nebuchadnezzar's insanity [G. V. Smith]. In the so-called standard inscription read by Sir H. Rawlinson, Nebuchadnezzar relates that during four (?) years he ceased to lay out buildings, or to furnish with victims Merodach's altar, or to clear out the canals for irrigation. No other instance in the cuneiform inscriptions occurs of a king recording his own inaction.

my counsellors ... sought unto me--desired to have me, as formerly, to be their head, wearied with the anarchy which prevailed in my absence (compare Note, see on Da 4:33); the likelihood of a conspiracy of the nobles is confirmed by this verse.

majesty was added--My authority was greater than ever before (Job 42:12; Pr 22:4; "added," Mt 6:33).
