'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 happened to be four lepers who were at that very moment at the entrance to the city gate. As they were talking with one another, they said, "Why are we sitting here waiting to die?

And when these lepers came to the uttermost part of the camp, they went into one tent, and did eat and drink, and carried thence silver, and gold, and raiment, and went and hid it; and came again, and entered into another tent, and carried thence also, and went and hid it.
