'Repealed' in the Bible

If it seems good to the king, let a royal decree go out from him and let it be written in the laws of Persia and Media, which cannot be repealed, that Vashti is never again to enter the presence of King Ahasuerus. Let the king give her royal position to another woman who is better than she.

Therefore, your majesty, establish the decree and sign the written document so it can't be changed, in accordance with the laws of the Medes and Persians that can't be repealed."

So they approached the king and asked, "Didn't you sign an edict that for the next 30 days if anyone prays to any god or man, except to you, your majesty, he would be thrown into the lions' pit?" The king responded, "The decree has been established, in accordance with the laws of the Medes and Persians that can't be repealed."

But the men who had gone as a group to the king told him, "Remember, your majesty, that according to the laws of the Medes and Persians, any decree or edict that the king establishes cannot be repealed."
