Mark 9 : 15

Greek εὐθὺς ('immediately') is a simple adverb; the Peshitta renders it with the periphrastic temporal phrase ܒܪ ܫܥܬܗ ('in that very hour/moment'), and the Vulgate uses confestim — all three convey immediacy, differing only in lexical packaging.

Greek uses the participle ἰδόντες plus pronoun αὐτόν; the Peshitta compresses both into the single suffixed verb ܚܙܐܘܗܝ ('they saw him'), while the Vulgate makes the object explicit by naming Jesum rather than employing a pronoun — a clarifying substitution of proper noun for pronoun.

Greek ἐξεθαμβήθησαν ('were utterly amazed') is a single aorist passive; the Vulgate renders this notion with a doubled expression, stupefactus est ('he/it was astounded') alongside expaverunt ('they were afraid'), reflecting a fuller amplification of the crowd's astonishment than the Greek or the single Syriac verb ܘܬܘܗܘ.

The connective καί / et joining the amazement to the approach is preserved in Greek and Latin; the Peshitta omits an explicit conjunction here, the waw being already prefixed to ܘܬܘܗܘ and ܘܪܗܛܘ, so the syntactic linkage is carried morphologically rather than by a freestanding particle.
