'One' in the Bible

You have sown much, but harvest little; you eat, but there is not enough to be satisfied; you drink, but there is not enough to become drunk; you put on clothing, but no one is warm enough; and he who earns, earns wages to put into a purse with holes.”

Then Haggai said, “If one who is unclean from a corpse touches any of these, will the latter become unclean?” And the priests answered, “It will become unclean.”

But now, do consider from this day onward: before one stone was placed on another in the temple of the Lord,

from that time when one came to a grain heap of twenty measures, there would be only ten; and when one came to the wine vat to draw fifty measures, there would be only twenty.
