Rude
From BiblePortal Wikipedia
Rude [1]
rōōd : Not "impolite" in English Versions of the Bible (except perhaps 2 Maccabees 12:14 ), but "untrained," "ignorant"; compare the modern phrase, "a rude drawing." So Sirach 8:4 ( ἀπαίδεντος , apaı́deutos ) and 2 Corinthians 11:6 ( ἰδιώτης , idiṓtēs , 'though I lack technical training in rhetoric'); compare the King James Version and the Revised Version margin Sirach 21:24.
