'Generation' in the Bible

And Joseph died and all of his brothers and all of that generation.

And God said again to Moses, "So you must say to the {Israelites}, 'Yahweh, the God of your ancestors, the God of Abraham, the God of Isaac, and the God of Jacob, has sent me to you. This [is] my name forever, and this [is] my remembrance from generation [to] generation.'

And he said, "Because a hand [was] against the throne of Yah, a war [will be] for Yahweh with Amalek from generation [to] generation."
