'Plague' in the Bible

So Gad went to David, told him the choices, and asked him, “Do you want three years of famine to come on your land, to flee from your foes three months while they pursue you, or to have a plague in your land three days? Now, think it over and decide what answer I should take back to the One who sent me.”

So the Lord sent a plague on Israel from that morning until the appointed time, and from Dan to Beer-sheba 70,000 men died.

And Araunah said, Wherefore is my lord the king come to his servant? And David said, To buy the threshingfloor of thee, to build an altar unto the LORD, that the plague may be stayed from the people.

And David built there an altar unto the LORD, and offered burnt offerings and peace offerings. So the LORD was intreated for the land, and the plague was stayed from Israel.
