From the early Church Fathers to now.
“There was a certain Levite, who dwelt on the side of mount Ephraim, who took a wife of Bethlehem Juda:”
“How full of pitiful traits is this story! A man, it says, a Levite, had taken to himself a wife, who I suppose was called a concubine from the word concubitus. She some time afterwards, as is likely to happen, offended at certain things, returned to her father and was with him four months.”
“A Levite, more courageous than wealthy, lived in the region of Mount Ephrem, for his tribe was allotted a landed possession far removed in place of the right of inheritance. He took a wife from the tribe of Bethlehem of Judah. While they felt the first attraction of their love deeply and equally, he continued to burn with unbounded desire for his wife. Yet her ways were different. His passion for her intensified until he inwardly seethed with desire. Yet, because there was a difference in their ages, and because he felt—either because she seemed to love him less or due to the violence of his pain—that she didn't consider him her equal, he used to criticize her. Frequently quarreling followed, and the offended wife gave back the keys of the house and went home.”
The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
