21 For the Lord shall rise up as in mount Perazim, he shall be wroth as in the valley of Gibeon, that he may do his work, his strange work; and bring to pass his act, his strange act.
English Standard Version
21 For the Lord will rise up as on Mount Perazim; as in the Valley of Gibeon he will be roused; to do his deed--strange is his deed! and to work his work--alien is his work!
21 God will rise to full stature, raging as he did long ago on Mount Perazim And in the valley of Gibeon against the Philistines. But this time it's against you. Hard to believe, but true. Not what you'd expect, but it's coming.
New King James Version
21 For the Lord will rise up as at Mount Perazim, He will be angry as in the Valley of Gibeon-- That He may do His work, His awesome work, And bring to pass His act, His unusual act.
New Living Translation
21 The Lord will come as he did against the Philistines at Mount Perazim and against the Amorites at Gibeon. He will come to do a strange thing; he will come to do an unusual deed:
Here is a promise of Christ, as the only foundation of hope for escaping the wrath to come. This foundation was laid in Zion, in the eternal counsels of God. This foundation is a stone, firm and able to support his church. It is a tried stone, a chosen stone, approved of God, and never failed any who made trial of it. A corner stone, binding together the whole building, and bearing the whole weight; precious in the sight of the Lord, and of every believer; a sure foundation on which to build. And he who in any age or nation shall believe this testimony, and rest all his hopes, and his never-dying soul on this foundation, shall never be confounded. The right effect of faith in Christ is, to quiet and calm the soul, till events shall be timed by Him, who has all times in his own hand and power. Whatever men trust to for justification, except the righteousness of Christ; or for wisdom, strength, and holiness, except the influences of the Holy Ghost; or for happiness, except the favour of God; that protection in which they thought to shelter themselves, will prove not enough to answer the intention. Those who rest in a righteousness of their own, will have deceived themselves: the bed is too short, the covering too narrow. God will be glorified in the fulfilling of his counsels. If those that profess to be members of God's church, make themselves like Philistines and Canaanites, they must expect to be dealt with as such. Then dare not to ridicule the reproofs of God's word, or the approaches of judgements.
