The power of Satan's voice is an important theme throughout Paradise Lost. Here, the emphasis is on the actual sound of Satan's voice and how it renovates the fallen angels' despair. At other moments in the poem his voice is just as effective, though it achieves different results; he uses it to trick Eve, for example, in Book 9, whereas in the early books his speeches seduce us (as readers) into admiring him.

"His thoughts were low,
Much like Satan, Belial (described here) is a bad dude; he's just as dangerous too because he "pleases the ear" with "persuasive accent[s]." Milton often points out the way in which what is "pleasing" can cause us to ignore someone's love for "vice." The voice, not just Satan's but God's as well, is a very powerful force in Paradise Lost.
