'Eternally' in the Bible

“This God, our God forever and ever—He will always lead us.”

That he should live on eternally,That he should not undergo decay.

though the wicked sprout like grassand all evildoers flourish,they will be eternally destroyed.

because he didn’t kill me in the wombso that my mother might have been my grave,her womb eternally pregnant.

Then I heard the man dressed in linen, who was above the waters of the river. He raised both his hands toward heaven and swore by Him who lives eternally that it would be for a time, times, and half a time. When the power of the holy people is shattered, all these things will be completed.
