Matthew Henry Commentary 2 Chronicles 14:1-15

"So Abijah slept with his fathers, and they buried him in the city of David; and Asa his son reigned in his stead. In his days the land was quiet ten years. And Asa did that which was good and right in the eyes of Jehovah his God: for he took away the foreign altars, and the high places, and brake down the pillars, and hewed down the Asherim, and commanded Judah to seek Jehovah, the God of their fathers, and to do the law and the commandment. Also he took away out of all the cities of Judah the high places and the sun-images: and the kingdom was quiet before him. And he built fortified cities in Judah; for the land was quiet, and he had no war in those years, because Jehovah had given him rest. For he said unto Judah, Let us build these cities, and make about them walls, and towers, gates, and bars; the land is yet before us, because we have sought Jehovah our God; we have sought him, and he hath given us rest on every side. So they built and prospered. And Asa had an army that bare bucklers and spears, out of Judah three hundred thousand; and out of Benjamin, that bare shields and drew bows, two hundred and fourscore thousand: all these were mighty men of valor. And there came out against them Zerah the Ethiopian with an army of a thousand thousand, and three hundred chariots; and he came unto Mareshah. Then Asa went out to meet him, and they set the battle in array in the valley of Zephathah at Mareshah. 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. So Jehovah smote the Ethiopians before Asa, and before Judah; and the Ethiopians fled. And Asa and the people that were with him pursued them unto Gerar: and there fell of the Ethiopians so many that they could not recover themselves; for they were destroyed before Jehovah, and before his host; and they carried away very much booty. And they smote all the cities round about Gerar; for the fear of Jehovah came upon them: and they despoiled all the cities; for there was much spoil in them. They smote also the tents of cattle, and carried away sheep in abundance, and camels, and returned to Jerusalem." — 2 Chronicles 14:1-15 (ASV)

Asa aimed at pleasing God and studied to commend himself to him. Happy are those who walk by this rule: not to do what is right in their own eyes, or in the eye of the world, but what is right in God's sight.

We find by experience that it is good to seek the Lord, for it gives us rest. While we pursue the world, we meet with nothing but vexation.

Asa consulted with his people how to make good use of the peace they enjoyed, and concluded with them that they must not be idle, nor complacent. A formidable army of Ethiopians invaded Asa's kingdom. This evil came upon them so that their faith in God might be tried.

Asa's prayer is short, but it is the genuine language of faith and expectation from God. When we go forth in God's name, we cannot fail to prosper, and all things work together for the good of those whom he favors.
