'Third' in the Bible

thou shalt not bow down thyself unto them, nor serve them; for I, Jehovah, thy God, am a jealous God, visiting the iniquity of the fathers upon the children, and upon the third and upon the fourth generation of them that hate me;

The children of the third generation that are born unto them shall enter into the assembly of Jehovah.

When thou hast made an end of tithing all the tithe of thine increase in the third year, which is the year of tithing, then thou shalt give it unto the Levite, to the sojourner, to the fatherless, and to the widow, that they may eat within thy gates, and be filled.
