'Thousand' in the Bible

(The LORD God of your fathers make you a thousand times so many more as ye are, and bless you, as he hath promised you!)

but showing faithful love to a thousand generations of those who love Me and keep My commands.

Know therefore that the LORD thy God, he is God, the faithful God, which keepeth covenant and mercy with them that love him and keep his commandments to a thousand generations;

How should one chase a thousand, and two put ten thousand to flight, except their Rock had sold them, and the LORD had shut them up?

He said:The Lord came from Sinaiand appeared to them from Seir;He shone on them from Mount Paranand came with ten thousand holy ones,with lightning from His right hand for them.
