Jamieson, Fausset and Brown on Nahum 3:11

hid--covered out of sight: a prediction remarkably verified in the state in which the ruins of Nineveh have been found [G. V. Smith]. But as "hid" precedes "seek strength," &c., it rather refers to Nineveh's state when attacked by her foe: "Thou who now so vauntest thyself, shalt be compelled to seek a hiding-place from the foe" [Calvin]; or, shalt be neglected and slighted by all [Maurer].

seek strength because of the enemy--Thou too, like Thebes (Na 3:9), shalt have recourse to other nations for help against thy Medo-Babylonian enemy.
