'Subscribe' in the Bible

One shall say, I am Jehovah's; and another shall call himself by the name of Jacob; and another shall subscribe with his hand unto Jehovah, and surname himself by the name of Israel.

Men shall buy fields for money, and subscribe the deeds, and seal them, and call witnesses, in the land of Benjamin, and in the places about Jerusalem, and in the cities of Judah, and in the cities of the hill-country, and in the cities of the lowland, and in the cities of the South: for I will cause their captivity to return, saith Jehovah.
