Boaz of Obed: The birth of Obed, the child of Boaz and Ruth and grandchild of Naomi, is described in considerable detail in Ruth 4.13-17.

Obed of Jesse: Jesse was the father of King David and of several other sons. The precise number of sons is uncertain. But only seven are specifically mentioned here in verses 13-15.

La Biblia: Traducción en Lenguaje Actual provides a possible model for the format of verses 10-12 as follows:

• The descendants of Ram were:
Amminadab,
Nahshon,
Salma, Boaz,
Obed,
Jesse.
Nahshon was a leader of the descendants of Judah.
