'Year of' in the Bible

(On the fifth of the month, which was in the fifth year of King Jehoiachin’s captivity,

It came about in the sixth year [of the captivity of King Jehoiachin], on the fifth day of the sixth month, as I sat in my house [near Babylon] with the elders of Judah sitting before me, that the hand of the Lord God fell on me there.

Again in the ninth year [of King Jehoiachin’s captivity by Nebuchadnezzar of Babylon], in the tenth month, on the tenth [day] of the month, the word of the Lord came to me, saying,

In the tenth year [of the captivity of King Jehoiachin by the king of Babylon], in the tenth month, on the twelfth of the month, the word of the Lord came to me, saying,

In the twelfth year of our exile [in Babylon], on the fifth of the tenth month, a survivor from Jerusalem came to me, saying, “The city has been captured.”

In the twenty-fifth year of our exile [in Babylon], in the beginning of the year, on the tenth [day] of the month, in the fourteenth year after the city [of Jerusalem] was taken, on that [very] same day the hand of the Lord was upon me and He brought me there.

But if he gives a gift from his inheritance to one of his servants, then it shall be his until the year of liberty [the Year of Jubilee]; after that it shall be returned to the prince. His inheritance shall be only his sons’ [permanently]; it shall belong to them.
