• Apali (verses 1-2): “Luke wrote this banana leaf/letter for Theophilus and spoke. ‘Theophilus,’ he said. ‘Long ago I wrote one banana leaf/letter for you and gave it and it (letter) went, as for that, I wrote about the fact that Jesus began and did work,’ he said. ‘I wrote about the fact that Jesus taught the men and women,’ he said. ‘I wrote about the fact that while God’s Spirit was giving Jesus strength, he (Jesus) habitually spoke to the men that he himself (Jesus) chose [apostles] for the purpose of telling talk,’ he said. ‘I tied a last talk on a banana leaf/letter about the fact that God got Jesus and went, and then I gave it (letter) and it (letter) went,’ he said. ‘As for the one banana leaf I wrote and gave it and it went, I will again write this one and give it and it will go,’ he said.” (source: Martha Wade in The Bible Translator 2009. p. 93ff. )
