John Gill 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)

And Asa cried unto the Lord his God
Or prayed, as the Targum, with vehemence, being in distress; this he did before the battle began, at the head of his army, and for the encouragement of it:

and said, Lord, [it is] nothing with thee to help ;
nothing can hinder from helping, his power being superior to all others, and even infinite, and none besides him could:

whether with many, or with them that have no power ;
numbers make no difference with him, nor the condition they are in; whether numerous and mighty, or few and feeble; he can as easily help the one as the other, see (1 Samuel 14:6) ,

help us, O Lord our God ;
who are few and weak in comparison of the enemy:

for we rest on thee ;
trust in thee, and rely upon thee for help; the Targum is,

``on your Word we lean:''

and in your name we go against this multitude ;
expressing faith in him, expecting help from him, encouraging and strengthening themselves in him, going forth not in their own name and strength, but in his; the Targum is,

``in the name of the Word of the Lord:''

O Lord, you [are] our God :
and you only we know, and serve no other, and we are your people, called by your name: let not man prevail against thee ;
for should this enemy prevail against them, it would be interpreted prevailing against their God.
