'Thousand' in the Bible

And they that had eaten were about five thousand men, beside women and children.

And they that did eat were four thousand men, beside women and children.

Do ye not yet understand, neither remember the five loaves of the five thousand, and how many baskets ye took up?

Neither the seven loaves of the four thousand, and how many baskets ye took up?

And when he had begun to reckon, one was brought unto him, which owed him ten thousand talents.
