'Save' in the Bible

All the presidents of the kingdom, the deputies and the satraps, the counsellors and the governors, have consulted together to establish a royal statute, and to make a strong interdict, that whosoever shall ask a petition of any god or man for thirty days, save of thee, O king, he shall be cast into the den of lions.

Then they came near, and spake before the king concerning the king's interdict: Hast thou not signed an interdict, that every man that shall make petition unto any god or man within thirty days, save unto thee, O king, shall be cast into the den of lions? The king answered and said, The thing is true, according to the law of the Medes and Persians, which altereth not.
