This represents genitive and dative forms of the second person singular pronoun: σου ('of you, your') and σοι ('to you, for you'). These forms appear constantly in biblical Greek, marking possession ('your house'), indirect objects ('I give to you'), and various prepositional relationships. The enclitic form σου could lose its accent when following another word, while σοι remained distinct. Ancient Greek's case system made these forms essential for indicating relationships between verbs and their personal objects. In direct discourse, prayers, and commandments, these forms created intimate personal address that modern English 'you' only partially captures.
