The Group Plans for Session 1 directs the leader to create four teams and assign each team a Bible passage (see third paragraph on page 21, Adult Leader Guide). The first passage suggested should be Matthew 22:41-45, not Matthew 23 as printed.
Thanks for using Explore the Bible and know we are praying for you as you begin this study of Hebrews.
ALSO: Leader Guide p. 20 under Explore the Text SHARE, the story of Elijah and the prophets of Baal is found in 1 Kings 18, not 2 Kings as printed.
Sandy, Thanks for bringing that to our attention. That should be 1 Kings.
