Jesus' Use Of Mountains In The Easter Context

I've written before about agreements among the gospels concerning some language Jesus used in the Easter context. In a post last year, I wrote about agreement among the gospels and Acts regarding Jesus' use of mountains. Something I didn't note in that post is that a couple of those passages are in the context of resurrection appearances. And they're in different documents written by different authors (Matthew 28:16, Acts 1:12). Something else they have in common is that both mountain settings seem to be ones Jesus chose ahead of time for some highly significant purpose (the Great Commission, the ascension) rather than just being a setting he chose for some lesser purpose (e.g., as a place to rest). So, these two resurrection accounts agree about that sort of behavior by Jesus, and similar behavior is seen in many non-resurrection contexts in all four of the gospels. Those characteristics add credibility to the accounts.
