'Thousand' in the Bible

Jesus gave them permission. And coming out, the unclean spirits entered the swine; and the herd rushed down the steep bank into the sea, about two thousand of them; and they were drowned in the sea.

There were five thousand men who ate the loaves.

About four thousand were there; and He sent them away.

when I broke the five loaves for the five thousand, how many baskets full of broken pieces you picked up?” They *said to Him, “Twelve.”

“When I broke the seven for the four thousand, how many large baskets full of broken pieces did you pick up?” And they *said to Him, “Seven.”
