'Sealed' in the Bible

I signed the deed and sealed it. I called in witnesses and used scales to weigh out the silver.

Then I took the deed of purchase both the sealed one with the terms and conditions and the open one

"This is what the LORD of the Heavenly Armies, the God of Israel, says: "Take these deeds both this sealed deed of purchase and this open deed and put them in a clay pot so they'll last for a long time.
