What does 2 Samuel 24:13 mean?

So Gad came to David, and told him, and said unto him, Shall seven years of famine come unto thee in thy land? or wilt thou flee three months before thy foes while they pursue thee? or shall there be three days’ pestilence in thy land? now advise thee, and consider what answer I shall return to him that sent me.

So Gad came to David, and told him, and said unto him, Shall seven years of famine come unto thee in thy land? or wilt thou flee three months before thine enemies, while they pursue thee? or that there be three days’ pestilence in thy land? now advise, and see what answer I shall return to him that sent me.

So Gad came to David, and told him, and said unto him, Shall seven years of famine come unto thee in thy land? or wilt thou flee three months before thy foes while they pursue thee? or shall there be three days’ pestilence in thy land? now advise thee, and consider what answer I shall return to him that sent me.

So Gad came to David, and gave him word of this and said to him, Are there to be three years when there is not enough food in your land? or will you go in flight from your haters for three months, while they go after you? or will you have three days of violent disease in your land? take thought and say what answer I am to give to him who sent me.

And Gad cometh in unto David, and declareth to him, and saith to him, `Do seven years of famine come in to thee in thy land? or three months art thou fleeing before thine adversary--and he pursuing thee? or are three days' pestilence in thy land? now, know and see what word I take back to Him sending me.'

And when Gad was come to David, he told him, saying: Either seven years of famine shall come to thee in thy land: or thou shalt flee three months before thy adversaries, and they shall pursue thee: or for three days there shall be a pestilence in thy land. Now therefore deliberate, and see what answer I shall return to him that sent me.

And Gad came to David, and told him, and said to him, Shall seven years of famine come to thee in thy land? or wilt thou flee three months before thine adversaries while they pursue thee? or shall there be three days' pestilence in thy land? Now be aware and consider what word I shall bring again to him that sent me.
