In the Greek text in Acts 2:47, the Textus Receptus, Tregelles’ GNT, and Von Soden’s, those three alone have σωζομένους, and Tyndale and the KJV render it “such as should be saved.  But all the other Greek editions have σῳζομένους, and render it something like “those who were being saved.   If anyone has insights on the Greek manuscript basis for the TR reading, let me know.
