'Couple' in the Bible

"We have nothing here," they said, "but five loaves and a couple of fish."

"How many loaves have you?" He inquired; "go and see." So they found out, and said, "Five; and a couple of fish."

"You yourselves," He said, "must give them food." "We have nothing," they replied, "but five loaves and a couple of fish, unless indeed we were to go and buy provisions for all this host of people."

"There is a boy here with five barley loaves and a couple of fish: but what is that among so many?"
