This is from a thanksgiving hymn in the Dead Sea Scrolls translated by Geza Vermes.
Calling to mind the might of Thy hand.
and the greatness of they compassion,
I rose and stood, and my Spirit was established.
in the face of the scourge.
I lean on Thy grace
and the multitude of Thy mercies.
for Thou will pardon iniquity,
and through your righteousness.
Thou will purify man of his sin.
Not for his sake wilt Thou do it.
but for the sake of Thy glory.
