This is τούτοις, the neuter plural dative form of the demonstrative, meaning 'to/for these things,' 'by these means,' or 'in these matters.' The neuter plural was crucial in Greek for referring to abstract collections, multiple facts, or classes of things. The dative case indicated indirect objects, means, or location ('in these things'). Biblical writers used it for phrases like 'by these means,' 'to these matters,' or 'in these circumstances.' It allowed compact reference to multiple items or complex situations without repetition. The form was especially common in theological and ethical discourse where writers needed to refer to sets of principles, teachings, or conditions previously mentioned.
