Charles Ellicott Commentary 1 Samuel 18:26

"And when his servants told David these words, it pleased David well to be the king`s son-in-law. And the days were not expired;" — 1 Samuel 18:26 (ASV)

It pleased David well. —The king’s design succeeded well, and the prospect of the alliance with Saul spurred on this brave soldier to more daring achievements, and yet wilder feats of arms. The savage, half-barbarous state of the age, however, comes prominently into view when we reflect upon the ferocious cruelty of such an offer being made and accepted, and carried out with even more than the required number of victims.
