And there was no day like that before it or after it, that the LORD hearkened unto the voice of a man: for the LORD {f} fought for Israel.

(f) By taking away the enemies hearts and destroying them with the hail stones.

Wesley's Notes

10:14 No day like that - Namely, in those parts of the world in which he here speaks, vain therefore is that objection, that the days are longer near the northern and southern poles, where they are constantly longer at certain seasons, and that by the order of nature; whereas the length of this day was purely contingent, and granted by God in answer to Joshua's prayer. The Lord hearkened to a man - Namely, in such a manner to alter the course of nature, and of the heavenly bodies, that a man might have more time to pursue and destroy his enemies. The Lord fought - This is added as the reason why God was so ready to answer Joshua's petition, because he was resolved to fight for Israel, and that in a more than ordinary manner. But this stupendous miracle was designed for something more, than to give Israel light to destroy the Canaanites. It was designed to convince and confound those idolaters, who worshipped the sun and moon, by demonstrating, that these also were subject to the command of the God of Israel: as also to signify, that in the latter days, when the world was covered with darkness, the sun of righteousness, even our Joshua, should arise, and be the true light of the world. To which we may add, that when Christ conquered our enemies upon the cross, the miracle wrought on the sun was the reverse of this. It was then darkened, as if going down at noon. For Christ needed not the light of the sun, to compleat his victory: so he made darkness his pavilion.

Matthew Henry's Concise Commentary

10:7-14 The meanest and most feeble, who have just begun to trust the Lord, are as much entitled to be protected as those who have long and faithfully been his servants. It is our duty to defend the afflicted, who, like the Gibeonites, are brought into trouble on our account, or for the sake of the gospel. Joshua would not forsake his new vassals. How much less shall our true Joshua fail those who trust in Him! We may be wanting in our trust, but our trust never can want success. Yet God's promises are not to slacken and do away, but to quicken and encourage our endeavours. Notice the great faith of Joshua, and the power of God answering it by the miraculous staying of the sun, that the day of Israel's victories might be made longer. Joshua acted on this occasion by impulse on his mind from the Spirit of God. It was not necessary that Joshua should speak, or the miracle be recorded, according to the modern terms of astronomy. The sun appeared to the Israelites over Gibeon, and the moon over the valley of Ajalon, and there they appeared to be stopped on their course for one whole day. Is any thing too hard for the Lord? forms a sufficient answer to ten thousand difficulties, which objectors have in every age started against the truth of God as revealed in his written word. Proclamation was hereby made to the neighbouring nations, Behold the works of the Lord, and say, What nation is there so great as Israel, who has God so nigh unto them?
