Mark 14:36 And he said, Abba, Father, all things are possible unto thee...
Is there any way to know if Jesus actually said, "Father, Father" ("Abba, Abba") here, with Mark leaving the first "Abba" untranslated so readers would know the actual word spoken by Jesus when addressing God?
Or did Jesus say "Abba" only once, with Mark adding the Greek translation "Pater" immediately afterwards? Also I'm wondering if Paul's two quotations in Romans 8:15 and Galatians 4:6, that seemingly derive from Mark 14:36, have any significance as related to this question.
