Nahum may have been in Judah at the time he recorded his prophecy. (Na 1:15)

Sometime after the Egyptian city of No-amon (Thebes) suffered humiliating defeat in the seventh century B.C.E. (3:8-10), the book of Nahum was committed to writing, being completed before Nineveh’s foretold destruction came in 632 B.C.E.​—See ASSYRIA; NINEVEH.
