'Generations' in the Bible

Who hath wrought and done it, calling the generations from the beginning? I, Jehovah, the first, and with the last, I am he.

For the moth shall eat them up like a garment, and the worm shall eat them like wool; but my righteousness shall be for ever, and my salvation unto all generations.

Awake, awake, put on strength, O arm of Jehovah; awake, as in the days of old, the generations of ancient times. Is it not thou that didst cut Rahab in pieces, that didst pierce the monster?

And they that shall be of thee shall build the old waste places; thou shalt raise up the foundations of many generations; and thou shalt be called The repairer of the breach, The restorer of paths to dwell in.

Whereas thou hast been forsaken and hated, so that no man passed through thee, I will make thee an eternal excellency, a joy of many generations.

And they shall build the old wastes, they shall raise up the former desolations, and they shall repair the waste cities, the desolations of many generations.
