'Schemes' in the Bible

Jerusalem, wash your evil from your heart so that you may be delivered. How long will you harbor evil schemes within you?

"What right does my beloved have in my house, when she has carried out many evil schemes? Can sacrificial flesh turn disaster away from you, so you can rejoice?"

I was like a gentle lamb led to the slaughter. I didn't know that they had devised schemes against me. They told themselves, "Let's destroy the tree with its fruit. Let's eliminate him from the land of the living, so his name won't be remembered again."
