Chronicles II 20:16 Meaning and Commentary

2 Chronicles 20:16

Tomorrow go ye down against them
This was the fast day, and so not proper to march out in, but on the morrow they might go out with great confidence and intrepidity; and as Jerusalem was situated on an eminence, they are directed to go down: behold, they come up by the cliff of Ziz;
a steep hill, so called from the flowers upon it: and ye shall find them at the end of the brook;
on the bank of Kidron, according to Beckius, which seems not likely to be meant, since they went as far as the wilderness of Tekoa, ( 2 Chronicles 20:20 ) , before the wilderness of Jeruel;
the same with that of Tekoa, or near it.
