The number of chapters does not matter, the number of words is what counts. Actually, the number of letters would be even better.

This question is actually interesting and gives you a chance to consider how the Bible was compiled. Psalms is actually a combination of many books, maybe as many as five. The question is what is the longest book in the Bible. That depends... What are you considering a book? Are you following our modern version or origional? Also, consider that many books and many have been split into a 1st and 2nd, but were origionally a single book.

Consider these points, at something like 43,000 words Psalms is the longest book in the Bible. However, since it is actually 5 books combined into one, I would not consider it to be the longest. It would easy to combine multiple books into a single, or split a single book into multiples. So I think you have to go back to the origional books to do a valid comparison like this.

At 42,000 words and being a single book in every version of the Bible, Jeremiah is actually the longest single book in the Bible.

Psalms with 150 chapters. It contains the longest chapter 119 with 176 verses and the shortest chapter is 117 with only 2 verses. Now the middle verse in the bible is psalms 118 verse 8.
