Question:  Why does AV7 show some words in  italics ?

Answer:  Words shown in  italics  in The AV7 Bible text are shown that way to clearly identify them as interpolatively added words in order to distinguish them from word-for-word translated words.

This practice has been used for more than 400 years ago, and it is continued in The AV7 Bible to help readers instantly recognize this very important distinction.

Interpolatively added words (in italics) are sometimes used to clarify the meaning of certain verses while preserving readers' ability to visually recognize the word-for-word literal translation accuracy in the text.

Interpolatively added words are also sometimes used to clarify who is speaking to whom by replacing non-descript pronouns such as,  "He said to him ..."  with something much clearer like this, for example:

  "Jesus  said to  John  ..." 

There are several additional benefits that become apparent in being able to quickly, visually distinguish between literal word-for-word translated words and interpolatively added words shown in italics as one reads the Bible.
