'Believed' in the Bible

And to whom sware he that they should not enter into his rest, but to them that believed not?

For we which have believed do enter into rest, as he said, As I have sworn in my wrath, if they shall enter into my rest: although the works were finished from the foundation of the world.

By faith the harlot Rahab perished not with them that believed not, when she had received the spies with peace.
