Thayer's Lexicon page 300. 1. Joshua, captian "OF" the Israelites. 2. Jesus, son "OF" Eliezer. 3. Jesus, the Son "OF" God. I see a lot of the word "OF", however, I don't see any "IN's". If you want to claim the word "in" to fit your interpretation of Gal 2:16, so be it, but you have not shown me proof that "in" fits better than the word "of".
The word "of" is not there. I just quoted it to you. It's not there. you gave the word for Jesus. I gave you the Greek reason that the English translation of "in" is proper. You ignored it. You however have supplied, well, nothing. Except for claiming that Ιησους means "of" when the source you quoted says "Jesus."
