The Psalms have been at the heart of Jewish and Christian devotion. They reflect every human experience and, as it were, allow us to talk about it before and with God. Here we start off with a sense of gratitude. Things have not been going too well, with even death a possibility (v.3).
Isaiah 40 describes God’s call of ‘the prophet’ who, though some Christian interpretation asserts as Jesus, is actually the emperor Cyrus, liberator of the Jews from exile in Babylon.
