The Magen David Series - Isaiah
From 619-533 B.C.E., Yishyahu was a prophet and poet for the Judean nobility. Many of his prophecies unfolded during his lifetime, and we still await his others of final Redemption to come true. However, he is clear in his writings that this will not come about with insincerity and empty prayers to G-d. Only through purity and holiness will it arrive.
