1 Chronicles 10:1-14 NIV
Saul Takes His Life
1Now the Philistines fought against Israel; the Israelites fled before them, and many fell dead on Mount Gilboa. 2The Philistines were in hot pursuit of Saul and his sons, and they killed his sons Jonathan, Abinadab and Malki-Shua. 3The fighting grew fierce around Saul, and when the archers overtook him, they wounded him.
4Saul said to his armor-bearer, “Draw your sword and run me through, or these uncircumcised fellows will come and abuse me.”
But his armor-bearer was terrified and would not do it; so Saul took his own sword and fell on it. 5When the armor-bearer saw that Saul was dead, he too fell on his sword and died.
6So Saul and his three sons died, and all his house died together.
7When all the Israelites in the valley saw that the army had fled and that Saul and his sons had died, they abandoned their towns and fled. And the Philistines came and occupied them.
8The next day, when the Philistines came to strip the dead, they found Saul and his sons fallen on Mount Gilboa. 9They stripped him and took his head and his armor, and sent messengers throughout the land of the Philistines to proclaim the news among their idols and their people. 10They put his armor in the temple of their gods and hung up his head in the temple of Dagon.
11When all the inhabitants of Jabesh Gilead heard what the Philistines had done to Saul, 12all their valiant men went and took the bodies of Saul and his sons and brought them to Jabesh. Then they buried their bones under the great tree in Jabesh, and they fasted seven days.
13 Saul died because he was unfaithful To The LORD; he did not keep The WORD of The LORD and even consulted a medium for guidance, 14and did not inquire of The LORD. So The LORD Put him to death and Turned the kingdom over to David son of Jesse.
Saul’s Death in Moral Reflections
The present chapter contains two facts not found in 1 Samuel 31:1-13 - the fastening of Saul's head in the temple of Dagon 1 Chronicles 10:10, and the burial of his bones, and those of his sons, under an oak 1 Chronicles 10:12. Otherwise the narrative differs from 1 Samuel 31:1-13 only by being abbreviated (see especially 1 Chronicles 10:6-7, 1 Chronicles 10:11-12), and by having some moral reflections attached to it 1 Chronicles 10:13-14.
All his house died together - Not the whole of his family, nor even "all his sons" (see 2 Samuel 2:8-15; 2 Samuel 3:6-15; 2 Samuel 4:1-12). The phrase is perhaps an abbreviation of the expression in the parallel passage of Samuel 1 Samuel 31:6.
For his transgression - Compare 1 Chronicles 9:1. The "transgression" intended is probably the disobedience with respect to Amalek, recorded in 1 Samuel 15:1-9 (compare 1 Samuel 28:17-18).
