A frequent misinterpretation portrays Saul's marriage offer as a sincere act of honor or reconciliation, ignoring his candid admission of plotting to use Michal as a deadly snare against David via Philistine aggression, which sanitizes Saul's treacherous envy and overlooks the narrative's emphasis on divine favor shifting from Saul to the faithful David despite human scheming.
I Samuel 18:21
King James Version (1769)
21 And Saul said, I will give him her, that she may be a snare to him, and that the hand of the Philistines may be against him. Wherefore Saul said to David, Thou shalt this day be my son in law in the one of the twain.
This passage exposes King Saul's duplicitous heart amid his escalating jealousy toward David; outwardly offering his daughter Michal in marriage to make David his son-in-law, Saul inwardly schemes for her to ensnare David, provoking the Philistines to kill him and thus eliminating a rival without direct bloodshed, illustrating the peril of unchecked envy and the contrast between Saul's cunning malice and David's unwitting loyalty.
