'Generation' in the Bible

Surely there shall not one of these men of this evil generation see the good land, which I sware to give unto your fathers,

And the days in which we came from Kadesh-barnea, until we were come over the brook Zered, were thirty and eight years; until all the generation of the men of war were consumed from the midst of the camp, as Jehovah sware unto them.

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;

A bastard shall not enter into the assembly of Jehovah; even to the tenth generation shall none of his enter into the assembly of Jehovah.

An Ammonite or a Moabite shall not enter into the assembly of Jehovah; even to the tenth generation shall none belonging to them enter into the assembly of Jehovah for ever:

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

And the generation to come, your children that shall rise up after you, and the foreigner that shall come from a far land, shall say, when they see the plagues of that land, and the sicknesses wherewith Jehovah hath made it sick;

They have dealt corruptly with him, they are not his children, it is their blemish; They are a perverse and crooked generation.

And he said, I will hide my face from them, I will see what their end shall be: For they are a very perverse generation, Children in whom is no faithfulness.
