Judges 16:3

Went away — The watch — men not expecting him 'till morning, and therefore being now retired into the sides, or upper part of the gate — house, as the manner now is, to get some rest, to fit themselves for their hard service intended in the morning: nor durst they pursue him, whom they now again perceived to have such prodigious strength, and courage; and to be so much above the fear of them, that he did not run away with all speed, but went leisurely. Hebron — Which was above twenty miles from Gaza. And Samson did this not out of vain ostentation, but as an evidence of his great strength, for the encouragement of its people to join with him vigorously; and for the greater terror and contempt of the Philistines. It may seem strange that Samson immediately after so foul a sin should have courage and strength from God, for so great a work. But first, It is probable, that Samson had in some measure repented of his sin, and begged of God pardon and assistance. This singular strength and courage was not in itself a grace, but a gift, and it was such a gift as did not so much depend on the disposition of his mind, but on the right ordering of his body, by the rule given to him, and others of that order.
