Charles Ellicott Commentary 2 Chronicles 20:4

"And Judah gathered themselves together, to seek [help] of Jehovah: even out of all the cities of Judah they came to seek Jehovah." — 2 Chronicles 20:4 (ASV)

To ask. —Literally, to seek (baqqesh, a synonym of dârash. 2 Chronicles 20:2) from Jehovah; namely, help, which the Authorised Version rightly supplies.

Even out of all the cities of Judah. —Emphasising the fact that the gathering in the Temple represented the whole nation. Syriac and Arabic, “and even from the distant cities.”
