John Gill Commentary 2 Chronicles 15:4

"But when in their distress they turned unto Jehovah, the God of Israel, and sought him, he was found of them." — 2 Chronicles 15:4 (ASV)

But when they in their trouble did turn unto the Lord God of
Israel
When being carried captive by neighbouring nations, and oppressed; and they cried unto the Lord, and repented of their sins, and turned from them to him:

and sought him ;
by prayer and supplication:

he was found of them ;
and appeared for their help and deliverance, of which there are many instances in the book of Judges.
