In Judges 19, what did the Levite do to the body of his dead concubine

He chopped her body into twelve pieces and sent a piece to each tribe of Israel.

When he was come into his house, he took a knife, and laid hold on his concubine, and divided her, together with her bones, into twelve pieces, and sent her into all the coasts of Israel. Judges 19:29

I took my concubine, and cut her in pieces, and sent her throughout all the country. Judges 20:16
