When commenting on Ps. 1, Bugenhagen begins by saying that the "blessed man" is Christ, but then he quickly moves to describing the difference between the godly and ungodly on the basis of the Psalm.
He is comparing the Latin Vulgate text with not just the Hebrew, but also the Greek. He explains all the words of the first verse and deals with the "old man and new man" within each Christian, repentance, being "at the same time just and sinner," and a lot more. For example, Bugenhagen explains that "meditate" means not just to think about something, but "by thinking to speak and exercise something." Meditation on God's Word is like playing a flute, where one's whole mind, heart, breath, and body is concentrated on the music.
On p. 8 he refers to "our Philipp’s" translation of Ps. 1:5. What work or translation is this? He also speaks against those who suppose there are contradictions in Scripture, on the issue of Ps. 1:5, where the Vulgate says the ungodly "will not arise in the judgment." What this actually means, he says, is that the ungodly will not come to their senses, even though they hear the judgment of God's Word, which the congregation of the righteous speaks.
At the end of his comments on Ps. 1, he says, "Therefore in this Psalm you have the scope of all of Holy Scripture."
