'Year of' in the Bible

(On the fifth day of the month -- it was the fifth year of King Jehoiachin's exile --

In the twelfth year of our exile, in the tenth month, on the fifth of the month, a refugee came to me from Jerusalem saying, "The city has been defeated!"

In the twenty-fifth year of our exile, at the beginning of the year, on the tenth day of the month, in the fourteenth year after the city was struck down, on this very day, the hand of the Lord was on me, and he brought me there.

But if he gives a gift from his inheritance to one of his servants, it will be his until the year of liberty; then it will revert to the prince. His inheritance will only remain with his sons.
