'Changes' in the Bible

So the king of Aram said, Go then; and I will send a letter to the king of Israel. And he went, taking with him ten talents of silver and six thousand shekels of gold, and ten changes of clothing.

And he said, All is well: but my master has sent me, saying, Even now, two young men of the sons of the prophets have come to me from the hill-country of Ephraim; will you give me a talent of silver and two changes of clothing for them?

And Naaman said, Be good enough to take two talents. And forcing him to take them, he put two talents of silver in two bags, with two changes of clothing, and gave them to his two servants to take before him.
