The original word

marah (מָרָה) — to be bitter, contentious, rebellious; the same word used for Israel's rebellion at Marah

What most readers miss in Isaiah 1:20

The phrase 'mouth of Yahweh has spoken' is a legal formula — this isn't a threat, it's a settled verdict

Common misconceptionPeople think God is being harsh here. Actually, He's being merciful — He's warning them about consequences they're already choosing, giving them time to repent.
