In conclusion, the backgrounding model and temporal-sequencing models are not applicable to all preposed clauses. The most plausible formulations of the theory apply exclusively to subject-preposed clauses; thus, object-preposing and adjunct-preposing are not afforded an explanation. Furthermore, many subject-preposed clauses do not describe backgrounded or nonsequential events and cannot be accounted for within these models.— Word Order in the Biblical Hebrew Finite Clause, page 31
