Dāna: Giving
Dāna is generosity, the open hand. Two hundred loaves and the dressed sheep came down the ravine ahead of any argument, and David took them from her hand before he took her point. A gift changes the air the way food set on a table quiets a quarrel, and here it bought the room in which a man could listen at all.
Paratoghosa: The voice of another
Paratoghosa is the outside word that turns a mind toward what is right. "I have listened to your voice" credits the whole reversal to something David did not arrive at on his own, a woman who came out to meet him on the road with better sense than his own. Much of what saves a person comes out of somebody else's mouth, the way a shout stops someone about to step into traffic.
Khanti: Forbearance
Khanti is bearing an insult without striking back. Four hundred swords were already on the road and the oath to leave nothing of Nabal's alive by morning still stood, and the insult that lit it was every bit as galling after Abigail spoke as before. Restraint like this is closer to reining in a horse at full gallop than to never having felt the anger.
Avihiṃsā: Non-harming
Avihiṃsā is the resolve to do no violence. Granting her request meant the men of that household woke up the next morning with no idea how near the night had come, which is how most non-harming looks: nothing happens, and nobody thanks anyone for it. The sword already drawn is the one no one ever sees.
Mettā: Goodwill
Mettā is the wish for another's welfare. "Go up in peace to your house" sends Abigail back up the hill to the very man whose contempt started this, and the peace laid on that house covers him too, the household David had sworn to empty. Goodwill offered at the moment you hold the power to destroy carries a weight that goodwill offered from weakness never has.
