Isaiah 21:12

The morning cometh, and also the night The watchman's answer is designedly obscure. It may mean either that the seer has obtained no clear vision of the destiny in store for Edom; or that he foresees a transient gleam of prosperity to be followed by a new night of distress; or that hope is dawning for some and gloom settling down on others.

if ye will inquire The answer is not final; another time the purpose of Jehovah may be more clearly indicated, if Edom earnestly desires to know it. For return, comerender with R.V. marg. come again. It is impossible to suppose that "return" is used in the sense of "be converted to the worship of Jehovah." The words for "cometh," "inquire" (twice) and "come" are Aramaic.
