The sun [and] moon stood still in their habitation: at the light of thine arrows they went, [and] at the shining of thy glittering spear.
Ver. 11. The sun and moon stood still in their habitation] viz. In the days of Joshua, and upon his prayer, Joshua 10:12,13, whereupon one crieth out, O admirabilem piarum precum vim ac potentiam quibus etiam coelestia cedunt, &c: Oh the admirable power of prayer, that worketh wonders in heaven! and oh the heroic faith of Joshua, the trophies whereof he set in the very orbs of heaven.
At the light of thine arrows they went] By these shining arrows and glittering spears, some understand that terrible lightning, mixed with that horrible hail, Jos 10:11 with Exodus 10:23, and then it is figura plane poetica, a poetic expression; for the poets call lightning Dιος βελος, Jove's arrow. See the like Psalms 18:14. The huge hail stones were God's glittering spears, wherewith he slaughtered his enemies. Others suppose that these things are meant of the arms and weapons of the Israelites, called God's arrows and spears, because used at his command and ordered by him (as the sword of the Lord and of Gideon, Jdg 7:18). This sense Gualther liketh better, as most comfortable to Christian warriors, who fight the Lord's battles.
