'Four' in the Bible

Four people came, carrying a paralytic to him.

Those who had eaten were about four thousand. Then he sent them away.

"When the seven loaves fed the four thousand, how many baskets full of broken pieces did you take up?" They told him, "Seven."

Then he will send out his angels, and will gather together his chosen ones from the four winds, from the ends of the earth to the ends of the sky.
