The following is the definition of the word translated as many according to Strong’s dictionary. I have taken the liberty of including Luke chapter 1 verse 1 from many copies of different Bible translations that I have on my computer.
It should be noted that Luke a Gentile; was a constant companion to Paul, and as such he had the opportunity to interview many of the Apostles and possibly Mary (mother of Jesus ) as well as several other eye witnesses of Jesus life.
