1 Samuel 25:3

“Now the name of the man [was] Nabal, etc.] Which signifies a “fool”; one would think his parents should not give him this name, though it is a name proper enough to men in common; and Kimchi thinks this was a nickname, which men gave him agreeably to his genius and conduct, and which is not improbable: and the name of his wife Abigail; which signifies “my father’s joy”, he delighting in her for her wit and beauty, as follows: and [she was] a woman of good understanding, and of a beautiful countenance; she was not only of a good understanding in things natural, civil, and domestic, but in things spiritual, as her speech to David shows, and which, with her external form, completed her…”

“he was of the house of Caleb--of course, of the same tribe with David himself; but many versions consider Caleb ("dog") not as a proper, but a common noun, and render it, "he was snappish as a dog."”

“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. 1 Kings (1 Samuel) 25:4”

“25:3 Nabal: See 25:25 for insight into the irony of his name. • Unlike her husband, Abigail was a sensible and wise person, as the narrative shows.”

“good: Pro 14:1, Pro 31:26, Pro 31:30, Pro 31:31 was churlish: Sa1 25:10, Sa1 25:11, Sa1 25:17; Psa 10:3; Isa 32:5-7 and he was: Wehoo calibbee, literally, "and he was a Calebite;" but as the word cailev signifies a dog, the Septuagint has understood it as implying a man of canine disposition, and translated it, και ανθρωπος κυνικος, "and he was a doggish man." It is understood in the same way by the Syriac and Arabic. 1 Kings (1 Samuel) 25:4”
