John Gill Commentary 2 Chronicles 20:12

"O our God, wilt thou not judge them? for we have no might against this great company that cometh against us; neither know we what to do: but out eyes are upon thee." — 2 Chronicles 20:12 (ASV)

O our God will you not judge them ? &c.] Bring them to your bar, examine these facts alleged against them, convict them of injustice, and condemn and punish them for it:

for we have no might against the great company that comes against us ; for though the militia of the kingdom of Judah was very numerous, as described (2 Chronicles 17:14–19) yet on a sudden it might not be easy to gather it together; besides, it was nothing to put trust and confidence in; and if the Lord was not with them, their strength would be weakness, and they not able to withstand this numerous army:

neither we know what to do ; whether to attempt to muster the militia, and go out to meet them, or to shut up themselves in Jerusalem, and make the best defence they could:

but our eyes are upon you ; for advice and direction, for help and protection; the eyes of their bodies were lifted up in prayer to him, and the eyes of their souls, of faith, hope, expectation, and desire, were fastened on him.
