1 Samuel 31:12-13

Young's Literal Translation

¹² and all the men of valour arise, and go all the night, and take the body of Saul, and the bodies of his sons, from the wall of Beth-Shan, and come in to Jabesh, and burn them there,

¹³ and they take their bones, and bury [them] under the tamarisk in Jabesh, and fast seven days.
