At the beginning of David, Was his birth due to adultery?
Psalms 51: 5 Behold in inequity I was brought forth and in sin my mother conceived me.

I ask because when Samuel asked Jesse for his sons, he brought only 7, not David. 1 Samuel 17" 28 Eliab, David's oldest brother burned in anger at him. This was for more than just a moment's anger but a lifetime.

David was anointed in the house, in front of his whole family.

Just a thought.
