1st Chronicles 21:10

7 And God was not pleased with this thing; so he sent punishment on Israel.

8 Then David said to God, Great has been my sin in doing this; but now, be pleased to take away the sin of your servant, for I have done very foolishly.

9 Then the word of the Lord came to Gad, David's seer, saying,

10 Go and say to David, The Lord says, Three things are offered to you: say which of them you will have, so that I may do it to you.

11 So Gad came to David and said to him, The Lord says, Take whichever you will:

12 Three years when there will not be enough food; or three months of war, when you will go in flight before your haters, being in great danger of the sword; or three days of the sword of the Lord, disease in the land, and the angel of the Lord taking destruction through all the land of Israel. Now give thought to the answer I am to take back to him who sent me.

13 And David said to Gad, This is a hard decision for me to make: let me come into the hands of the Lord, for great are his mercies: let me not come into the hands of men.
