The Books of Enoch — True Church Edition
3 Enoch 48B
2And they give glory unto them and they answer and cry before them: Holy, Holy, Holy. And they roll (convoy) them through every heaven as mighty and honoured princes. And when they bring them all back to the place of the Throne of Glory, then all the Chayyoth by the Merkaba open their mouth in praise of His glorious name, saying: "Blessed be the name of His glorious kingdom for ever and ever".
