Chesed, the engine of the book
Chesed is the loyalty a person keeps when no law compels it. The word falls three times in Ruth and each time it is a hinge. Naomi releases her daughters-in-law with a blessing, 'May the LORD show you loving devotion, as you have shown to your dead and to me' (1:8). Naomi recognizes the same loyalty in God when she hears whose field Ruth gleaned in, 'who has not withdrawn His kindness from the living or the dead' (2:20). Boaz names it in Ruth at the threshing floor, 'You have shown more kindness now than before' (3:10). Human loyalty and God's own loyalty are described with one word, and the book lets the reader see them running together.

Providence under an ordinary surface
God speaks to no one in Ruth and performs no miracle. What the narrator says instead is that Ruth 'went out into the field and gleaned after the harvesters. And she happened to come to the part of the field belonging to Boaz' (2:3), the flattest possible description of the turn the whole book rests on. Naomi has already said aloud who is at work, having heard 'that the LORD had attended to His people by providing them with food' (1:6). Ruth is Scripture's clearest case of God governing history through harvest law, a field boundary, and one man's decency.

Empty, and filled
Naomi states the book's problem in her own words at the gate of Bethlehem: 'I went away full, but the LORD has brought me back empty' (1:21), and asks to be called Mara instead of Naomi. Nothing in the book argues with her. The answer comes as an event rather than an explanation, when the women tell her that her daughter-in-law 'is better to you than seven sons' (4:15) and she takes the child into her own lap (4:16).

The wings of refuge
Boaz blesses Ruth for having come to Israel's God, 'under whose wings you have taken refuge' (2:12). One chapter later Ruth asks him for the same thing in the same word, since kanaph carries both the wing of a bird and the skirt of a garment: 'Spread the corner of your garment over me, for you are a kinsman-redeemer' (3:9). The man who prayed the blessing is asked to become the answer to it, and he does.

The outsider brought all the way in
Ruth is called the Moabitess at 1:22, 2:2, 2:21, 4:5, and 4:10, so her origin is still being repeated in the chapter where she is married and bears a son. She names herself the same way at Boaz's feet, 'even though I am a foreigner' (2:10). What changed her standing was a confession she made on a road, 'your people will be my people, and your God will be my God' (1:16), and the book carries her from that sentence to a place in Israel's royal line without ever pretending she was born inside it.

The law kept, and then exceeded
Israel's harvest law left the corners and the dropped grain for the poor, the sojourner, and the widow (Leviticus 19:9-10; Deuteronomy 24:19). Ruth asks for more than that, to 'glean and gather among the sheaves after the harvesters' (2:7), and Boaz grants it and adds to it, telling his men to 'pull out for her some stalks from the bundles' (2:16). Chapter 4 shows the same movement in law rather than in grain: Boaz takes on a redemption the nearer kinsman was free to decline, and does it in front of ten elders at the gate.
