Fix typos

[thenewmantis]

• Fix typo. λάβε -> λαβέ, ᾰ -> ᾱ in nom + voc of Σωσίᾱς
• Fix typo. smooth-breathing -> grave

So λάβε is Koine while λαβέ is Attic. I am trying to write with a somewhat-atticising Koine, but decided that λάβε would be my preference in that particular instance. That's not a typo, but a conscious choice.

Thanks. I've fixed it so λάβε is preserved. For what it's worth, I am slightly new to Greek but have enough knowledge of declensions from Latin (and of the Greek accent system) that I can pick up on little details like this ... so if I show consistent misunderstanding on some more advanced thing just let me know.
