The Spirit of Jehovah came mightily upon him, and the ropes that were upon his arms became as flax that was burnt with fire, and his bands dropped off his hands. Judges 15:14
“Spirit of Jehovah” is an Old Testament phrase that describes the Holy Spirit. Whereas the name “God” tends to describe His absolute power in relationship to creation, the name “Jehovah,” or “Lord,” tends to describe His sovereign power in relationship to people. Just as the Spirit of Jehovah cam upon Samson to loose him from the two new ropes that bound him (Judges 15:13-14), so He can come upon you to give you victory over habits and addictions. Just as the Spirit of Jehovah came upon Othniel and Jephthah to give them victory in battle (Judges 3:9-10; 11:29), so He can give you victory over temptations and trials. Just as the Spirit of Jehovah enabled Gideon to call a courageous army together (Judges 6:34), so He can call all the forces of Heaven to your side.
The Holy Spirit is the Spirit of Jehovah who gave strength to the judges. He raised them up for leadership positions and gave them victory in battle. The judges were mere mortals, but the Spirit of Jehovah made the difference in their lives. What He has done for them, He can do for you.
