Psalms Chapter 118
Depending upon the Bible used, Psalms is the middle book with Psalm 117 as the middle chapter (KJV).
The Bible is divided into two sections: the Old Testament and the New Testament. The middle of the Bible would correspond to the middle of these two sections, which is the book of Psalms.
The term "middle aged" is not used in the Bible, but I suppose if it was used at the time it would have meant rather what it does today. The age of man in the Bible, the age a person before which a person might be said to have died before his time, was 70. I would think middle aged people would be those who were very roughly half way between being young adults of about 20, and the reasonably old age of 70, which would place it at 45 or so.
Yes, Samuel is considered a prophet in the Bible.
