Psalms 91:13 (KJV) states, "Thou shalt tread upon the lion and adder: the young lion and the dragon shalt thou trample under feet." This verse comes from Psalm 91, which is a powerful and comforting passage that speaks of God’s protection and deliverance for those who trust in Him.

In this particular verse, the psalmist uses vivid imagery to convey the idea of God’s ultimate victory over the forces of evil. The lion and adder are commonly used in the Bible as symbols of dangers and threats. The lion represents an enemy that is fierce and strong, while the adder, a type of venomous snake, is a metaphor for subtler and more treacherous dangers. The idea of treading upon these creatures and trampling them underfoot represents a powerful image of victory and control over these dangerous forces.

The context of Psalm 91 is one of assurance and confidence in God’s protection. The psalmist begins by declaring that those who dwell in the secret place of the Most High, who abide under the shadow of the Almighty, will find refuge and safety. The subsequent verses speak of God’s faithfulness in delivering His people from various perils, such as deadly pestilence, terror by night, and the destruction that lays waste at noonday. The psalmist expresses unwavering trust in God's ability to shield and defend those who put their trust in Him.

The overarching theme of Psalm 91:13, and the entire Psalm 91, is God’s sovereignty and protection. The verse emphasizes the idea that those who have faith in God will not only be protected from harm, but will also have the power to conquer and overcome the very things that may seek to destroy them. The imagery of treading upon the lion and adder further emphasizes the idea that God’s people, through His strength and might, have authority over the threats and dangers that may come their way.

This verse also carries with it echoes of spiritual warfare. In the Bible, the lion and the serpent are often associated with Satan, who is described as a roaring lion seeking whom he may devour (1 Peter 5:8) and a serpent who deceived Eve in the Garden of Eden (Genesis 3:1-6). By treading upon these dangerous creatures, the psalmist is declaring the victory of God’s people over the forces of darkness and evil. This imagery is reminiscent of the promise given in Luke 10:19 where Jesus says, "Behold, I give unto you power to tread on serpents and scorpions, and over all the power of the enemy: and nothing shall by any means hurt you."

The verse also speaks to the idea of God’s faithfulness in delivering His people from overwhelming odds. The picture of treading upon the lion and adder signifies an act of triumph and conquest over seemingly insurmountable adversaries. This reflects the enduring biblical theme of God’s ability to bring victory and deliverance for His people in the face of formidable challenges.

Overall, Psalm 91:13 serves as a powerful reminder of God’s unfailing protection and victorious power for those who trust in Him. It embodies the assurance that God is not only able to shield His people from harm, but He also empowers them to overcome the threats and dangers that they may encounter. It stands as a testament to the transformative strength and mighty authority that is granted to those who place their faith in God.
