'Sealed' in the Bible

And I subscribed the evidence, and sealed it, and took witnesses, and weighed him the money in the balances.

So I took the evidence of the purchase, both that which was sealed according to the law and custom, and that which was open:

Thus saith the LORD of hosts, the God of Israel; Take these evidences, this evidence of the purchase, both which is sealed, and this evidence which is open; and put them in an earthen vessel, that they may continue many days.

Fields will again be bought with silver, and deeds of purchase signed, sealed, and witnessed. This will happen in the territory of Benjamin, the villages surrounding Jerusalem, the towns in Judah, the southern hill country, the western foothills, and southern Judah. For I will restore them to their land. I, the Lord, affirm it!'"

So King Zedekiah made a secret promise to Jeremiah and sealed it with an oath. He promised, "As surely as the Lord lives who has given us life and breath, I promise you this: I will not kill you or hand you over to those men who want to kill you."
