John 7:19

There is no specific element in the phrase "Οὐ Μωϋσῆς δέδωκεν ὑμῖν τὸν νόμον" (Ou Mōysēs dedōken hymin ton nomon) that signifies interrogation. The statement is in the indicative mood, indicating a declarative statement rather than a question. It is a straightforward assertion that Moses did not give them the law. If there were an element of interrogation, it would typically involve question words such as "πῶς" (pōs, "how"), "τίς" (tis, "who"), or "μή" (mē, "not") used in a way to form a question.
