Charles Ellicott Commentary 2 Kings 20:14

"Then came Isaiah the prophet unto king Hezekiah, and said unto him, What said these men? and from whence came they unto thee? And Hezekiah said, They are come from a far country, even from Babylon." — 2 Kings 20:14 (ASV)

What did these men say? —“Isaiah, with that fearless assumption of a superior position which we have noticed in Isaiah 7:0, at once challenges the king to explain his conduct. Jehovah’s will is opposed to all dallying with foreign powers. (Compare to Isaiah 30:1.)” [ Cheyne.]

From a far country. —So the Assyrian kings describe Palestine as “a far off land,” using the same adjective (rûqu).
