Peter Leithart writes fascinatingly on Ruth
"Ruth adorns herself as a bride, but she also dresses herself as a priest... As 2 Chronicles says, the temple was built on the piece of property that David purchased from Araunah or Ornan, the threshing floor on Mount Moriah. Ruth prepares like a priest in order to approach her husband on the threshing floor. Israelites reading Ruth after the building of the temple would think of the temple and its worship... Ruth seeks a husband on the threshing floor near Bethlehem, and Israel sought her husband Yahweh at the temple built on a threshing floor. We too come to worship, washing, anointed, and clothed by our baptisms, and we come to seek our husband. We are adorned as priests, and as the bride."
