Matthew Henry on Judges 13:24-25

The Spirit of the Lord began to move Samson when a youth. This was evidence that the Lord blessed him. Where God gives his blessing, he gives his Spirit to qualify for the blessing. Those are blessed indeed in whom the Spirit of grace begins to work in the days of their childhood. Samson drank no wine or strong drink, yet excelled in strength and courage, for he had the Spirit of God moving him; therefore be not drunk with wine, but be filled with the Spirit.
