'Write in a Book' in the Bible

And Samuel will speak to the people the judgment of the kingdom; and he will write in a book and put before Jehovah. And Samuel will send away all the people, a man to his house.

And I shall write in a book, and seal and affirm witnesses, and weigh the silver in the balances.

I am the Alpha and the Omega, the first and the last: and, What thou seest, write in a book, and send to the seven churches which in Asia; to Ephesus, and to Smyrna, and to Pergamos, and to Thyatira, and to Sardis, and to Philadelphia, and to Laodicea.
