'Devices' in the Bible

But I was like a gentle lamb that is led to the slaughter; and I didn't know that they had devised devices against me, [saying], Let us destroy the tree with its fruit, and let us cut him off from the land of the living, that his name may be no more remembered.

But they say, It is in vain; for we will walk after our own devices, and we will do everyone after the stubbornness of his evil heart.

Then they said, Come, and let us devise devices against Jeremiah; for the law shall not perish from the priest, nor counsel from the wise, nor the word from the prophet. Come, and let us strike him with the tongue, and let us not give heed to any of his words.
