A reader has kindly made an eSword version of Targum Lamentations available. I do not use this tool myself, but Jonathan’s directions were these:
I’m sorry it has taken me so long to get this to you. I have attached the E-Sword file for you of your Targum. The file just needs to be copied into the E-sword program folder (c:\program files (x86)\E-Sword in most cases). When E-sword is started it will be included in the Topic files. For the Newest version of E-sword it will be in Resource Library. I would have put it as a Bible, but due to time and the fact that we are only dealing with a single book I thought this format would be easier. Let me know if you have any questions or if you would like any changes made.
