Ruth 2:19b-23

When Naomi heard that Boaz was that man, she responded with a prayer (v20), what do you think she was acknowledging (vv19b-20)?  What does kinsman-redeemer means (Lev 25:23-25; Deut 25:5-10)?  What was Naomi’s advice for Ruth (vv21-23)?  What have we learnt about God’s and Boaz’s kindness to the weak, needy and widowed in Deut 24:19-22 and Ruth 2?
