For thou preventest him with the blessings of goodness: thou settest a crown of pure gold on his head.
Thou preventest - surprisest him with blessings even exceeding his request (cf. 2 Samuel 7:18-19).
Settest a crown. God's promise of the everlasting continuance of the kingdom to David's seed was in David's eyes a crowning of him anew, with a crown of preciousness far exceeding all the glory which he already enjoyed. He was not only an "Abimelech," or King's father, as distinguished from an elective monarchy, but father of a royal and everlasting seed.
