All three render the inceptive verb 'they began' (ἤρξαντο / cœperunt); in Syriac the conjunction and the inchoative verb are fused into a single prefixed form ܘܫܪܝܘ, so the Peshitta index 0 carries both the 'and' and the 'began' senses.
EN They began to salute him, “Hail, King of the Jews!”
ES Comenzaron luego á saludarle: ¡Salve, Rey de los Judíos!
ZH-HANS 就庆贺他说:「恭喜,犹太人的王啊!」
ZH-HANT 就慶賀他說:「恭喜,猶太人的王啊!」

Greek and Latin express the act with a verb of greeting plus accusative object (ἀσπάζεσθαι αὐτόν / salutare eum), whereas the Peshitta uses the idiomatic Syriac construction ܠܡܫܐܠ ܒܫܠܡܗ, literally 'to ask after his peace/welfare,' a periphrastic salutation formula built on the root sh-l-m rather than a single verb of greeting.
Greek χαῖρε ('rejoice/hail') is a Hellenic greeting imperative, the Vulgate matches with Ave, but the Peshitta employs ܫܠܡ ('peace'), the standard Semitic salutation, substituting the native shalom-greeting for the Greek mocking acclamation.
Greek attests the vocative with the nominative-form article ὁ βασιλεῦ (a Semitising vocative-with-article idiom); both Latin rex and Syriac ܡܠܟܐ render the title without an article, the Vulgate dropping the article per Latin grammar and the Peshitta marking it with the emphatic state.
