'Thousand' in the Bible

And it will come to pass in that day, in every place where there used to be a thousand vines, worth a thousand silver shekels, there will be briars and thorns.

A thousand of you will flee at the threat of one man;You will flee at the threat of five,Until you are left like a flag on the top of a mountain,And like a signal on a hill.

So now, exchange pledges with my master the king of Assyria and I will give you two thousand horses, if you are able on your part to put riders on them.

“The smallest one will become a thousand (a clan),And the least one a mighty nation.I, the Lord, will quicken it in its [appointed] time.”
