'Thousand' in the Bible

There were about five thousand men who ate, besides women and children.

And those who ate were four thousand men, besides women and children.

Do you not yet understand or remember the five loaves of the five thousand, and how many baskets full you picked up?

Or the seven loaves of the four thousand, and how many large baskets full you picked up?

When he had begun to settle them, one who owed him ten thousand talents was brought to him.
