I was reading a Bible here, and it contains the following sentence
damit du die Gewißheit der Dinge erkennst, in denen du unterrichtet worden bist.
I am trying to understand, which tense is here and how it should be translated
du bist unterrichtet worden
If does not look like passive in some tense, because passive should be constructed as werden + Partizip II
, so I am lost... Can somebody explain all the steps which produce this sentence?
