Judges 13:5 - Joseph Benson’s Commentary on the Old and New Testaments

The child shall be a Nazarite Consecrated to God's service in a peculiar manner. He shall begin to deliver Israel He did not complete the deliverance of the Israelites from the servile yoke of the Philistines; but the work was carried on and perfected by others, namely, by Eli, Samuel, and Saul, and especially by David. Samson galled them severely, but they still continued to oppress Israel, as they did when he was born, and the oppression continued, more or less, till the memorable victory of Ebenezer, recorded 1 Samuel 7:13, when they were subdued, and their tyranny of forty years ended. Thus God chooses to carry on his work gradually, and by several hands. One lays the foundation of a good work, another builds, and perhaps a third brings forth the top-stone.
