The story of Ruth. That was what the Jesse Tree readings brought us today. I've always liked the story of Ruth and Naomi and Boaz - but it's not a story my children are familiar with - and the selected readings only gave part of the story (Ruth 1:16; 2:2, 8, 10-12; 4:13-14). Unfortunately today was one of those days when circumstances collide to give us not much time - so instead of reading the story in full or giving them a complete explanation, I gave them a short version of who Ruth was.
The second reading (Matthew 1:5b-61) lets us know that Ruth and Boaz were the great-grandparents of King David and therefore Jesus' ancestors.
