Epistle of Barnabas 16:5b “For the Writing says: ‘And it will come to pass in the last days that the Lord will deliver the sheep of His pasture, and the sheepfold, and their tower to destruction.’ And it took place according to what the Lord said.”

What Writing was Barnabas referring to? Was it 1 Enoch?

1 Enoch 89:56 “And I saw that He forsook their house and their tower and gave them all into the hand of the lions and into the hand of all the wild beasts to tear and devour them.”
