'Devotion' in the Bible

Naomi said to her two daughters-in-law, "Listen to me! Each of you should return to your mother's home! May the Lord show you the same kind of devotion that you have shown to your deceased husbands and to me!

He said, "May you be rewarded by the Lord, my dear! This act of devotion is greater than what you did before. For you have not sought to marry one of the young men, whether rich or poor.
