Samson Destroys The Philistines.
Then Samson called to the Lord, saying, “O Lord God, remember me, I pray! Strengthen me, I pray, just this once, O God, that I may with one blow take vengeance on the Philistines for my two eyes!” Judges 16:28 NKJV
How they were destroyed. Samson pulled the house down upon them, God no doubt putting it into his heart, as a public person, thus to avenge God's quarrel with them, Israel's, and his own.
He gained strength to do it by prayer, That strength which he had lost by sin he, like a true penitent, recovers by prayer; as David, who, when he had provoked the Spirit of grace to withdraw, prayed (Psalm 51:12), Restore unto me the joy of thy salvation, and uphold me with thy free Spirit. We may suppose that this was only a mental prayer, and that his voice was not heard (for it was made in a noisy clamorous crowd of Philistines); but, though his voice was not heard of men, yet his prayer was heard of God and graciously answered, and though he lived not to give an account himself of this his prayer, as Nehemiah did of his, yet God not only accepted it in heaven, but, by revealing it to the inspired penmen, provided for the registering of it in his church. He prayed to God to remember him and strengthen him this once, thereby owning that his strength for what he had already done he had from God, and begged it might be afforded to him once more, to give them a parting blow. That it was not from a principle of passion or personal revenge, but from a holy zeal for the glory of God and Israel, that he desired to do this, appears from God's accepting and answering the prayer. Samson died praying, so did our blessed Saviour; but Samson prayed for vengeance, Christ for forgiveness.
He gained opportunity to do it by leaning on the two pillars which were the chief supports of the building, and were, it seems, so near together that he could take hold of them both at one time. Having hold of them, he bore them down with all his might, crying aloud, Let me die with the Philistines. - Matthew Henry
