Albert Barnes Commentary 2 Chronicles 14:11

"And Asa cried unto Jehovah his God, and said, Jehovah, there is none besides thee to help, between the mighty and him that hath no strength: help us, O Jehovah our God; for we rely on thee, and in thy name are we come against this multitude. O Jehovah, thou art our God; let not man prevail against thee." — 2 Chronicles 14:11 (ASV)

It is nothing ... - that is, you can as easily help the weak as the strong.
