What does Ruth 4:11 mean?

All the people at the gate and the elders said, 'We are witnesses. May the Lord make this woman, who is coming into your home, like Rachel and Leah, who built up the family of Israel. May you prosper in Ephrathah and be famous in Bethlehem.' Ruth 4:11 - Modern Text Bible

(The community blesses Boaz and Ruth, hoping their family will be as important as the great mothers of Israel.)
