Yea, cry unto him against the power of your enemies.
Yea, cry unto him against the devil, who is an enemy to all righteousness.
The parallelism of the first phrases is quite obvious. In the second phrase, we have the parallels of the enemies and the devil. If we have Amulek citing a poem with expansions, we would expect the “who is an enemy to all righteousness” to be such an expansion.
