"Go and tell David, 'This is what the LORD says: I am giving you three options. Choose one of them for me to carry out against you.' "
So Gad went to David and said to him, "Shall there come upon you three years of famine1 in your land? Or three months of fleeing from your enemies while they pursue you? Or three days of plague2 in your land? Now then, think it over and decide how I should answer the one who sent me."

David said to Gad, "I am in deep distress. Let us fall into the hands of the LORD, for his mercy3 is great; but do not let me fall into the hands of men."
