'Generation' in the Bible

“How great are His signsAnd how mighty are His wonders!His kingdom is an everlasting kingdomAnd His dominion is from generation to generation.

“But at the end of that period, I, Nebuchadnezzar, raised my eyes toward heaven and my reason returned to me, and I blessed the Most High and praised and honored Him who lives forever;For His dominion is an everlasting dominion,And His kingdom endures from generation to generation.
