To search Old and New Testament Abstracts by passage/pericope, use EITHER the Scriptures button OR the Scripture Reference index under Indexes.
Otherwise, these databases function much as the Atla Religion Database.
Linked Full Text would be just that, whereas SEATTLE PACIFIC UNIV and Books might return items that could be scanned (Bible "Commentary" Available via SPU Scanning).
As with the Atla Religion Database, there are at least three other ways to search in addition to By passage. For more on this, see under General Comments (with links), above.
