'Generation' in the Bible

And with many more appeals he solemnly warned and entreated them, saying, "Escape from this crooked generation."

That Tent was bequeathed to the next generation of our forefathers. Under Joshua they brought it with them when they were taking possession of the land of the Gentile nations, whom God drove out before them. So it continued till David's time.

For David, after having been useful to his own generation in accordance with God's purpose, did fall asleep, was gathered to his forefathers, and did undergo decay.
