'Signify' in the Bible

and one of them, by name Agabus, having stood up, did signify through the Spirit a great dearth is about to be throughout all the world -- which also came to pass in the time of Claudius Caesar --

now, therefore, ye, signify ye to the chief captain, with the sanhedrim, that to-morrow he may bring him down unto you, as being about to know more exactly the things concerning him; and we, before his coming nigh, are ready to put him to death.'

for it doth seem to me irrational, sending a prisoner, not also to signify the charges against him.'
