'Certificate' in the Bible

“It was said, ‘Whoever sends his wife away, let him give her a certificate of divorce’;

They asked him, "Why, then, did Moses order us "to give a certificate of divorce and divorce her'?"

They said, "Moses allowed a man to write a certificate of divorce and to divorce her."

If I am not [considered] an apostle to others, at least I am one to you; for you are the seal and the certificate and the living evidence of my apostleship in the Lord [confirming and authenticating it].

He erased the certificate of debt, with its obligations, that was against us and opposed to us, and has taken it out of the way by nailing it to the cross.
