'Third' in the Bible

You shall not worship them or serve them; for I, the Lord your God, am a jealous (impassioned) God [demanding what is rightfully and uniquely mine], visiting (avenging) the iniquity (sin, guilt) of the fathers on the children [that is, calling the children to account for the sins of their fathers], to the third and the fourth generations of those who hate Me,

Their children of the third generation who are born to them may enter the assembly of the Lord.

“When you have finished paying all the tithe of your produce the third year, [which is] the year of tithing, then you shall give it to the Levite, to the stranger, to the orphan, and to the widow, so that they may eat within the gates of your cities and be satisfied.
