John Gill Bible Commentary

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 Sa1 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 thy Word we lean:" and in thy 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, thou art our God: and thou only we know, and serve no other, and we are thy people, called by thy name: let not man prevail against thee; for should this enemy prevail against them, it would be interpreted prevailing against their God.
