Here is, I. Asa's general character (Ch2 14:2): He did that which was good and right in the eyes of the Lord his God. 1. He aimed at pleasing God, studied to approve himself to him. Happy are those that walk by this rule, to do that which is right, not in their own eyes, or in the eye of the world, but in the eyes of God. 2. He saw God's eye always upon him, and that helped much to keep him to what was good and right. 3. God graciously accepted him in what he did, and approved his conduct as good and right.

II.A blessed work of reformation which he set on foot immediately upon his accession to the crown. 1. He removed and abolished idolatry. Since Solomon admitted idolatry, in the latter end of his reign, nothing had been done to suppress it, and so, we presume, it had got ground. Strange gods were worshipped and had their altars, images, and groves; and the temple service, though kept up by the priests (Ch2 13:10), was neglected by many of the people. Asa, as soon as he had power in his hands, made it his business to destroy all those idolatrous altars and images (Ch2 14:3, Ch2 14:5), they being a great provocation to a jealous God and a great temptation to a careless unthinking people. He hoped by destroying the idols to reform the idolaters, which he aimed at, rather than to ruin them. 2. He revived and established the pure worship of God; and, since the priests did their part in attending God's altars, he obliged the people to do theirs (Ch2 14:4): He commanded Judah to seek the Lord God of their fathers, and not the gods of the heathen, and to do the law and the commandments, that is, to observe all divine institutions, which many had utterly neglected. In doing this, the land was quiet before him, Ch2 14:5. Though they were much in love with their idols, and very loth to leave them, yet the convictions of their consciences sided with the commands of Asa, and they could not, for shame, refuse to comply with them. Note, Those that have power in their hands, and will use it vigorously for the suppression of profaneness and the reformation of manners, will not meet with so much difficulty and opposition therein as perhaps they feared. Vice is a sneaking thing, and virtue has reason enough on its side to make all iniquity stop her mouth, Psa 107:42.

III.The tranquillity of his kingdom, after constant alarms of war during the last two reigns: In his days the land was quiet ten years ( Ch2 14:1), no war with the kingdom of Israel, who did not recover the blow given them in the last reign for a great while. Abijah's victory, which was owing, under God, to his courage and bravery, laid a foundation for Asa's peace, which was the reward of his piety and reformation. Though Abijah had little religion himself, he was instrumental to prepare the way for one that had much. If Abijah had not done what he did to quiet the land, Asa could not have done what he did to reform it; for inter arma silent leges - amidst the din of arms the voice of law is unheard.

IV.The prudent improvement he made of that tranquillity: The land had rest, for the Lord had given him rest. Note, If God give quietness, who then can make trouble? Job 34:29. Those have rest indeed to whom God gives rest, peace indeed to whom Christ gives peace, not as the world giveth, Joh 14:27. Now, 1. Asa takes notice of the rest they had as the gift of God (He hath given us rest on every side. Note, God must be acknowledged with thankfulness in the rest we are blessed with, of body and mind, family and country), and as the reward of the reformation begun: Because we have sought the Lord our God, he has given us rest. Note, As the frowns and rebukes of Providence should be observed for a check to us in an evil way, so the smiles of Providence should be taken notice of for our encouragement in that which is good. See Hag 2:18, Hag 2:19; Mal 3:10. We find by experience that it is good to seek the Lord; it gives us rest. While we pursue the world we meet with nothing but vexation. 2. He consults with his people, by their representatives, how to make a good use of the present gleams of peace they enjoyed, and concludes with them, (1.) That they must not be idle, but busy. Times of rest from war should be employed in work, for we must always find ourselves something to do. In the years when he had no war he said, "Let us build; still let us be doing." When the churches had rest they were built up, Act 9:31. When the sword is sheathed take up the trowel. (2.) That they must not be secure, but prepare for wars. In times of peace we must be getting ready for trouble, expect it and lay up in store for it. [1.] He fortified his principle cities with walls, towers, gates, and bars, Ch2 14:7. "This let us do," says he, "while the land is yet before us," that is, "while we have opportunity and advantage for it and have nothing to hinder us." He speaks as if he expected that, some way or other, trouble would arise, when it would be too late to fortify, and when they would wish they had done it. So they built and prospered. [2.] He had a good army ready to bring into the field (Ch2 14:8), not a standing army, but the militia or trained-bands of the country. Judah and Benjamin were mustered severally; and Benjamin (which not long ago was called little Benjamin, Psa 68:27) had almost as many soldiers as Judah, came as near as 28 to 30, so strangely had that tribe increased of late. The blessing of God can make a little one to become a thousand. It should seem, these two tribes were differently armed, both offensively and defensively. The men of Judah guarded themselves with targets, the men of Benjamin with shields, the former of which were much larger than the latter, Kg1 10:16, Kg1 10:17. The men of Judah fought with spears when they closed in with the enemy; the men of Benjamin drew bows, to reach the enemy at a distance. Both did good service, and neither could say to the other, I have no need of thee. Different gifts and employments are for the common good.

Targets and spears - Probably targets with the dagger in the center, and javelins for distant fight.

Bare shields and drew bows - They were not only archers, but had shield and sword for close fight.

And there came out against them Zerah the Ethiopian, with an host of thousand thousand, and three hundred chariots,.... According to Josephus (b), this army consisted of 900,000 foot, and 100,000 horsemen, and certain it is there were horsemen among them, Ch2 16:8 some say these were not the Ethiopians in Africa, beyond Egypt, being, as is said, too far off for such an army to travel, and it would be hard to say what should induce them to it; and besides it is urged, the king of Egypt would never have suffered them to pass through his dominions, as they must to come to Judea; but that they were the Cushite Arabs, that inhabited Midian, part of Arabia Petraea, and Arabia Felix, near Judaea; see Gill on Num 12:1, but since this great host consisted of Lubim or Libyans, inhabitants of Africa, as well as of Ethiopians, Ch2 16:8, these Ethiopians seem to be rather those in Africa, who were masters of Egypt and Libya, as well as Ethiopia, quickly after the death of Shishak, or Sesostris, see Ch2 12:2, which accounts for the size of this army, and their passage through Egypt: that there were two sorts of Ethiopians, the western and eastern ones, the one that dwelt in Africa, the other in Asia, appears clearly from Homer (c), Herodotus (d), and Heliodorus (e), the former of which seem here meant; nor need this army be thought incredible, especially since they were joined by the Lubim or Libyans, and assisted by the Philistines, as appears by what follows; besides, the two armies of Israel and Judah we read of in the preceding chapter, when put together, exceed this; see also Ch2 17:14, so the armies of Tamerlane and Bajazet, that of the former being 1,600,000, and that of the latter 1,400,000 (f):

and came unto Mareshah; a city in the tribe of Judah, on the borders of it, Ch2 11:8.

while the land is yet before us--that is, while we have free and undisputed progress everywhere; no foe is near; but, as this happy time of peace may not last always and the kingdom is but small and weak, let us prepare suitable defenses in case of need. He had also an army of five hundred eighty thousand men. Judah furnished the heavily armed soldiers, and Benjamin the archers. This large number does not mean a body of professional soldiers, but all capable of bearing arms and liable to be called into service.
