Today most of us read silently to ourselves. In Biblical times, this was not the case. Reading was to be done out loud…always! People in the ancient world would read the Bible out loud to “bring it to life.” Written words on scrolls and books were expensive and rare, so reading quietly to yourself wasn’t considered normal. The rarity and price of such written words conveyed a sense of community, to which the reader felt obligated to pronounce the readings loudly and give them life for all to hear.
A great example of this can be found in Acts 8:30 when Philip approaches an Ethiopian eunuch who is reading aloud from the book of Isaiah to no one but himself.
