Shmuel Alef 5:3-4

And when they of Ashdod arose early the next day, hinei, Dagon was fallen upon his face on the ground before the Aron HASHEM. And they took Dagon, and returned him to his makom. And when they arose baboker on the next day, hinei, Dagon was fallen upon his face on the ground before the Aron HASHEM; and the rosh Dagon and both the kapot (palms) of his hands were cut off upon the miftan (threshold); only the trunk of Dagon was left to him.
