'Collusion' in the Bible

So these supervisors and satraps came by collusion to the king and said to him, "O King Darius, live forever!

Then those officials who had gone to the king came by collusion and found Daniel praying and asking for help before his God.

Then those men came by collusion to the king and said to him, "Recall, O king, that it is a law of the Medes and Persians that no edict or decree that the king issues can be changed."
