About item number 5 - which was addressed as well in another topic recently - I am often drawn to think about episodes in chapters 13-15 of I Samuel. Things come to a head at chapter 15, verse 10 with this (NJB):
The word of Yahweh came to Sameuel, "I regret having made Saul king, since he has broken his allegiance to me and not carried out my orders." Samuel was appalled and cried to Yahweh all night llong.
In the morning, Samuel set off to find Saul....
17: "Yahweh has appointed you as the king of Israel. "When Yahweh sent you on a mission he said to you, 'Go and put those inners, the Amalekites, under the curse of destruction and make war on them until they are exterminated.' Why did you not obey Yahweh's voice? Why did you you fall on booty and do what is wrong in Yahweh's eyes?"
The situation has leaves much room for question on both sides? Are we to suppose that God had second thoughts about Saul? Or did Samuel who had misgivings about the appointment of a king in the first place? Would Saul have taken the higher road if he spared not a single Amalekite, but did as instructed via Samuel: "Now, go and crush Amale; put him under the curse of destruction with all that he possesses. Do not spare him, but kill man, and woman, babe and suckling, ox and sheep, camel and donkey."( 15:3).
(15:4) Saul summoned the people and reviewe dthem at Telaim: two hundred thousand foot soldiers ( and ten thousand men of Judah). Saul advanced on the town of Amalek and lay in ambush in the river bed.

There are a lot of problems with this story. Whether camels were domesticated in this presumed period is one matter that comes to mind. Whether a force of 200,000 would have existed anywhere circa 1000 BC is another matter; but if it did, it did not simply lie in ambush in a riverbed to take a tribal stronghold. The intent of this expedition was to punish Amalek for laying a trap for Israel as it had come up from Egypt.
So, who is talking? Yahweh or Samuel? Then, once Saul is discredited and disposed of, why is David such a terrific improvement?
