'Lepers' in the Bible

May it come on the head of Joab and all his father's family: among the men of Joab's family may there ever be some who are diseased or lepers, or who do the work of women, or are put to the sword, or are wasted from need of food!

Now there were four lepers seated at the doorway into the town: and they said to one another, Why are we waiting here for death?

And when those lepers came to the outer line of tents, they went into one tent, and had food and drink, and took from it silver and gold and clothing, which they put in a secret place; then they came back and went into another tent from which they took more goods, which they put away in a secret place.
