'Devices' in the Bible

But I was like a gentle lamb that is led to the slaughter; and I knew not that they had devised devices against me,'saying , Let us destroy the tree with the fruit thereof, 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 every one after the stubbornness of his evil heart.

Then said they, 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 smite him with the tongue, and let us not give heed to any of his words.
