'Decreed' in the Bible

Shimei replied to the king, "What your majesty has decreed is acceptable to me. I'll do what you've said." So Shimei lived in Jerusalem for quite some time.

so the king sent for Shimei and asked him, "Didn't I make a promise to the LORD and warn you, "The day you leave and go anywhere else, you can be sure you'll die'? And you told me, "What your majesty has decreed is acceptable to me.'

Later that same day, he gave them a special display of power of what was to come when he said, "Here's proof that the LORD has decreed this: Look! This altar will be split apart and the ashes that are on it will spill out."
