'Store' in the Bible

Upon the first day of the week let every one of you lay by him in store, as God hath prospered him, that there be no gatherings when I come.

Laying up in store for themselves a good foundation against the time to come, that they may lay hold on eternal life.

But the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men.
