Who through faith subdued kingdoms
As David did particularly; who subdued Syria, Moab, Ammon, Amalek, Edom, and the Philistines, ( 2 Samuel 8:12 2 Samuel 8:14 ) . War, in some cases, is lawful; and kingdoms may be subdued; and faith makes use of means to do it: these kingdoms, though subdued by faith, yet not without fighting. Believers have no reason to be afraid of kings, or kingdoms; and this should encourage the saints, in their combats with the powers of darkness.
exercised vindictive justice, in taking vengeance on the enemies of God, and his people; civil righteousness, in the discharge of their offices; and moral righteousness, in their conversation before God and men; which, being imperfect, was not justifying: wherefore they stood in need of another, and better righteousness, which is perfect and durable; and, in consequence of which being known, embraced, and received, men work righteousness: it may be observed, that to do works of righteousness in faith, and by it, is something very considerable; it is reckoned here among actions of the greatest fame; and that true faith is an operative grace, it works by love, and is always attended with works of righteousness; and that righteousness is a fruit and evidence of faith; and that faith is not the believer's righteousness; and that the righteousness of faith is not that which faith works, but which it receives.
the promise of the land of Canaan; particular promises of victory over their enemies; promises concerning the Messiah, and of everlasting life and happiness: their faith was not the cause of promises being made, nor of their being fulfilled; but was the grace by which these believers received them, believed them, and waited for the accomplishment of them; and, in some sense, enjoyed the things promised before hand; their faith realizing things future and invisible to them: to obtain a promise from God is a great and marvellous thing; it is an instance of rich grace; and there is never a promise, but what is great in itself, and precious to the saints: all God's promises are obtained; they are sure, and are certainly fulfilled; and it is the work and business of faith to receive, and enjoy them.
Stopped the mouths of lions:
a lion was slain by Samson, and another by David; but the most remarkable instance of stopping the mouths of lions, was in the den, into which Daniel was cast; and this may encourage the faith of God's people, when they are in the midst of men, comparable to lions; and may animate them not to fear the devouring lion, Satan.
