33 Но лю́ди ви́дели,

33 [But, Yet] people [have you seen, seen],

как они́ отплы́ли,

[how, what, as, like (comparison)] [they, they are] [sailed away, set sail],

причем мно́гие их узна́ли и устремились туда́ посуху из всех городо́в,

причем many [them, their] [found out, known, learned] and устремились there посуху [from, in, of, out] [all, everyone] [cities, city],

так что оказа́лись на ме́сте да́же ра́ньше ло́дки.

so [what, that, why] (turned out to be) [at, by, in, it, on the, to, toward, upon] location even [before, earlier] [boat, boats, ship, ships].

Now many saw them going and recognized them,
and they ran there on foot from all the towns and got there ahead of them.
Mark 6:33 ESV

And the people saw them departing,
and many knew him,
and ran afoot thither out of all cities,
and outwent them,
and came together unto him.
Mark 6:33 KJV
