'Generation' in the Bible

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

And the space in which we came from Kadeshbarnea, until we were come over the brook Zered, was thirty and eight years; until all the generation of the men of war were wasted out from among the host, as the LORD sware unto them.

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

A bastard shall not enter into the congregation of the LORD; even to his tenth generation shall he not enter into the congregation of the LORD.

An Ammonite or Moabite shall not enter into the congregation of the LORD; even to their tenth generation shall they not enter into the congregation of the LORD for ever:

The children that are begotten of them shall enter into the congregation of the LORD in their third generation.

So that the generation to come of your children that shall rise up after you, and the stranger that shall come from a far land, shall say, when they see the plagues of that land, and the sicknesses which the LORD hath laid upon it;

They have corrupted themselves, their spot is not the spot of his children: 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 froward generation, children in whom is no faith.
