'Year of' in the Bible

In the fifth [day] of the month, which was the fifth year of king Jehoiachin's captivity,

It happened in the twelfth year of our captivity, in the tenth [month], in the fifth [day] of the month, that one who had escaped out of Jerusalem came to me, saying, The city has been struck.

In the five and twentieth year of our captivity, in the beginning of the year, in the tenth [day] of the month, in the fourteenth year after that the city was struck, in the same day, the hand of Yahweh was on me, and he brought me there.

But if he give of his inheritance a gift to one of his servants, it shall be his to the year of liberty; then it shall return to the prince; but as for his inheritance, it shall be for his sons.
