A Bible reading marathon is returning to Washington this week. The event will begin at 8 a.m. Tuesday in Central Park. Event goers are asked to bring their own Bible, lawn chair, and water. It will run from 8 a.m. to 8 p.m. Tuesday and Wednesday, and 8 a.m. to 3 p.m. on Thursday. Readers will take turns reading passages from the Bible aloud from cover to cover.
