I received my UBS6 textual commentary today and notice that it perpetuates an error in the UBS5 critical apparatus on 1 Timothy 1:4. It says GA 0150 reads εκζητησεις, supporting the UBS reading, but in fact 0150 reads ζητησεις. But the commentary makes a good point of speculation, that the EC ending of the previous word was confused with EK in the beginning of εκζητησεις. I can see this easily happening with a scribe whose primary language was Latin.

In my understanding of the context, εκζητησεις fits better, meaning “uncertainties” as opposed to “furthering the program of God which is in faith.”
