'Famine' in the Bible

There [was] a famine in the days of David [for] three years, year after year. And David {inquired of Yahweh}, and Yahweh said, "The bloodguilt [is] on Saul and on his household, because he killed the Gibeonites."

Then Gad came to David, and he told him and said to him, "Shall seven years of famine in the land come to you? Or three months of your fleeing from your enemies while he [is] pursuing you? Or should there be three days of pestilence in your land? Now consider and decide what I must return to the one who sent me a word."
