'Reading' in the Bible

and he was returning and sitting in his chariot, and was reading the prophet Isaiah.

And Philip ran to him, and heard him reading Isaiah the prophet, and said, Understandest thou what thou readest?

Now the passage of the Scripture which he was reading was this, He was led as a sheep to the slaughter; And as a lamb before his shearer is dumb, So he openeth not his mouth:

And after the reading of the law and the prophets the rulers of the synagogue sent unto them, saying, Brethren, if ye have any word of exhortation for the people, say on.
