'Ever' in the Bible

For this reason, if food is a cause of trouble to my brother, I will give up taking meat for ever, so that I may not be a cause of trouble to my brother.

Who ever goes to war without looking to someone to be responsible for his payment? who puts in vines and does not take the fruit of them? or who takes care of sheep without drinking of their milk?

Love's ways are ever fair, it takes no thought for itself; it is not quickly made angry, it takes no account of evil;

In a second, in the shutting of an eye, at the sound of the last horn: for at that sound the dead will come again, free for ever from the power of death, and we will be changed.

For this cause, my dear brothers, be strong in purpose and unmoved, ever giving yourselves to the work of the Lord, because you are certain that your work is not without effect in the Lord.
