Who told you a little bit of Greek is a dangerous thing? Someone who only reads the KJV??
The nice thing about a little bit of Greek is that it turns into a lot of Greek. The more you learn, the more you study and search and read Greek. I've been reading Greek for quite a few years since my "semesters of Greek" and learning more and more about God's Word all the time. Sometimes amazing things that simply cannot come through in the English, because we don't have cases, or the vocative, or the same kind of verb tenses.
Hebrew too, for that matter. Just so much can NOT come through in the English.
No idea which panel or which men you are talking about. I took Greek from godly men, one of whom had been studying it for 60 years. Another who read the New Testament and the Septuagint straight from the Greek, without ever having to look up a concordance. Of course, maybe it makes a difference if you have a gift for languages. Apparently God has given me that gift, since I speak quite a few languages, which is unusual for North Americans, but not for Europeans. Or many other countries.
Greek is not that hard, if you understand English, French and German grammar and have a good memory for vocabulary and grammar.
