John Wesley on 1 Samuel 25:3

Abigail - That is, the joy of his father: yet he could not promise himself much joy of her, when he married her to such an husband: it seems, in inquiring, (no unfrequent thing) more after his wealth, than after his wisdom. Caleb - This is added to aggravate his crime, that he was a degenerate branch of that noble stock of Caleb, and consequently of the tribe of Judah, as David was.
