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.
You can find the file via this link (right-click or cntl-click and choose “save as”). For more information on this targum please see the TgLam section of this site.
