'Year of' in the Bible

Be careful not to think this wicked thought to yourselves: "The seventh year, the year of remission, is drawing near,' and you show ill will toward your poor relative and not give to him. He may then call to the LORD on account of you, and you will be guilty of sin.

"When you have finished your harvest, reserve the tithe in the third year (the year of the tithe), and give the entire tithe to the descendants of Levi, to the foreigners, to the orphans, and to the widows, so they may eat and be satisfied in your cities.
