Psalms 90-150

The Psalms, penned by at least 8 different people over many generations, are essentially worship song lyrics or hymnals. They cover the span of human emotions in relation to God, and are generally divided into five "books": 1-41, 42-72, 73-89, 90-106, and 107-150. But the New Testament seems to indicate that they also contain some prophecy, the primary topic of which is the Messiah and his coming kingdom. See the commentary linked below for more details.
