'Signify' in the Bible

Then Paul took the men, and the next day purifying himself with them entered into the temple, to signify the accomplishment of the days of purification, until that an offering should be offered for every one of them.

Now therefore ye with the council signify to the chief captain that he bring him down unto you to morrow, as though ye would inquire something more perfectly concerning him: and we, or ever he come near, are ready to kill him.

For it seemeth to me unreasonable to send a prisoner, and not withal to signify the crimes laid against him.
