rebellion: a stubborn refusal to listen to and obey the authority you are bound to, above all God
Hebrew has two ways of talking about rebelling. One is the language of revolt, throwing off a king, withholding tribute, taking up arms, and that belongs to a different verb (מָרַד, "to revolt"). This word belongs to the other family, built on the verb מָרָה, "to defy," and its picture is quieter and more stubborn. Someone has spoken, and you will not listen. Nearly every time the word appears, the voice being refused is God's.
That is why Samuel can set it beside the occult and mean it. When he tells Saul that "rebellion is as the sin of divination," the charge is not that Saul raised an army against God but that he heard a plain command and did as he pleased. Moses uses the same word for a whole generation's track record, pairing it with a stiff neck.
The word also does something unusual with people. Rather than calling them rebellious, Hebrew often calls them rebellion: "sons of rebellion," "a people of rebellion," and, over a dozen times in Ezekiel, "a house of rebellion." The effect is like naming a household after the family trade. Rebellion is not something these people occasionally do; it is what they are, one generation after another, and Ezekiel is warned not to catch it himself.
Only once does the word step outside that setting. In Proverbs it describes a troublemaker set on defying a human ruler, and what comes after him is a royal officer rather than the judgment of God.
