'Signed' in the Bible

And Daniel, on hearing that the writing had been signed, went into his house; (now he had windows in his room on the roof opening in the direction of Jerusalem;) and three times a day he went down on his knees in prayer and praise before his God, as he had done before.

Then they made answer and said before the king, Daniel, one of the prisoners of Judah, has no respect for you, O King, or for the order signed by you, but three times a day he makes his prayer to God.
