Thank you for sharing your husband’s dream with us. Please take everything that I say to the Holy Spirit as He alone gives the accurate interpretation. I believe that the Lord is encouraging your husband by telling him he is winning a spiritual warfare involving the enemy and other attacks. He is metaphorically “shutting the mouths of the lions.” I think of the story of Daniel in the lion’s den and the Lord sending his angel to shut the mouth of the lions.
May he begin to praise and thank the Lord for deliverance in Jesus is Almighty Name I pray, Amen!
