Aramaic translation of Psalm 137

[Aaron S]

The Peshitta TNK and it reads parallel to the Hebrew. The Targum of the Psalms reads as you have spoken. If you didn't know, neither of these texts were produced by Christians.
Here is Dr. Cook's translation of the verse in question:

5. The voice of the Holy Spirit* replies and says, "If I forget you, O Jerusalem, I will forget my right hand."
* Voice of the Holy Spirit: an echo from heaven.

As Cook's note hints at, we can liken this unto the spirit 'hovering' over the waters.
