'Signed' in the Bible

Therefore king Darius hath signed the writing and interdict.

And Daniel, when he hath known that the writing is signed, hath gone up to his house, and the window being opened for him, in his upper chamber, over-against Jerusalem, three times in a day he is kneeling on his knees, and praying, and confessing before his God, because that he was doing it before this.

then they have come near, yea, they are saying before the king concerning the king's interdict: 'Hast thou not signed an interdict, that any man who seeketh from any god and man until thirty days, save of thee, O king, is cast into a den of lions?' Answered hath the king, and said, 'The thing is certain as a law of Media and Persia, that doth not pass away.'

Then they have answered, yea, they are saying before the king, that, 'Daniel, who is of the sons of the Removed of Judah, hath not placed on thee, O king, any regard, nor on the interdict that thou hast signed, and three times in a day he is seeking his petition.'
