190. When did Saul become David's enemy?
After the dancing girls sang, "Saul has killed his thousands, and David his tens of thousands."
And it came to pass as they came, when David was returned from the slaughter of the Philistine, that the women came
out of all cities of Israel, singing and dancing, to meet king Saul, with tabrets, with joy, and with instruments
of musick. And Saul eyed David from that day and forward. 1 Samuel 18:8-9
After David bought Saul's daughter with 200 Philistine foreskins.
Wherefore David arose and went, he and his men, and slew of the Philistines two hundred men;
and David brought their foreskins, and they gave them in full tale to the king,
that he might be the king's son in law. And Saul gave him Michal his daughter to wife.
And Saul saw and knew that the LORD was with David, and that Michal Saul's daughter loved him.
And Saul was yet the more afraid of David; and Saul became David's enemy continually. 1 Samuel 18:27-29
