'Signed' in the Bible

I signed and sealed the deed, and called in witnesses, and weighed out the silver on the scales.

and I gave the deed of purchase to Baruch the son of Neriah, the son of Mahseiah, in the sight of Hanamel my uncle’s son and in the sight of the witnesses who signed the deed of purchase, before all the Jews who were sitting in the court of the guard.

Therefore King Darius signed the document, that is, the injunction.

Now when Daniel knew that the document was signed, he entered his house (now in his roof chamber he had windows open toward Jerusalem); and he continued kneeling on his knees three times a day, praying and giving thanks before his God, as he had been doing previously.

Then they answered and spoke before the king, “Daniel, who is one of the exiles from Judah, pays no attention to you, O king, or to the injunction which you signed, but keeps making his petition three times a day.”
