'Generation' in the Bible

It shall never be inhabited, neither shall it be dwelt in from generation to generation: neither shall the Arabian pitch tent there; neither shall shepherds make their flocks to lie down there.

And he hath cast the lot for them, and his hand hath divided it unto them by line: they shall possess it for ever; from generation to generation shall they dwell therein.
