Greek uses coordinating καί + aorist participle εἰσελθοῦσα ('and having entered'); the Vulgate renders this with the enclitic conjunction Cumque + pluperfect subjunctive introisset ('and when she had entered'), while the Peshitta uses a finite perfect ܥܠܬ ('she entered') coordinated by the prefixed waw in ܘܡܚܕܐ. The participial vs. finite-verb realisation is a routine translational adjustment.
