“If you remove from your midst oppression, false accusation, and malicious speech, if you bestow your bread on the hungry, and satisfy the afflicted, then light shall rise for you in the darkness,...and God will guide you always, and give you relief in desert places” (Isaiah 58:9–11).
Isaiah tries to describe what a just people and country would look like if they fasted from the right things. He uses lovely words like light, guidance, abundance, renewed strength, watered gardens, repairers and restorers, nurturance, and delight, “a spring that never fails,” and even “riding on the heights of the earth.” But it all depends on fasting from unkindness and choosing justice. It is this very passage speaking of “repair and restoration” (tikkun) that our Jewish brothers and sisters use today as their call to social justice.
