Go to נבל and say in my name there shall be peace in your household and peace in upon all that is yours. Since we did a favor for you and didn't steal your sheep we have come for your celebration to gather some food. Please give all you can to your servants and your son דוד.
דוד TALKING TO HIS MEN
So many people come to mourn for שמואל because he went from city to city to learn with בני ישראל (and when יהושע died בני ישראל didn't mourn enough for him so ד׳ brought an earthquake).
DELIVERING THE MESSAGE
Who is this דוד he is like a slave running away from his master and why should I give my bread and water and meat that I have slaughtered myself. Why should I give this to you if I don't even know you?
נבל is a very rich and snobby man. He is married to a beautiful and smart woman named אביגיל. He was at work sheering his sheep and he was about to make a feast to celebrate. A man asks him for money,but נבל says that he already gave money in מעון where he lives. When someone asks him for money at his house he says that he already gave money in כרמל where he works. So he never ends up giving צדקה.
+390 people went with דוד
"each man get your sword"
דוד called his men to tell נבל a message. (The navi asks why do דוד and his men need food? There are two answers: 1. It was ערב ראש השנה and he needed food for Yomtov 2. דוד and his men were hiding from שאול so they didn't eat for a long time and they were hungry).
What אביגיל did
+ 390 people
So the 10 young men went to go tell נבל everything that דוד had told them. But נבל said no. So they returned to דוד to tell him what נבל had said to them.
When the young men got back to דוד they told him everything that נבל had told them. דוד got really mad and decided that he wanted to kill נבל and everything that belonged to him so he said to his army "get your swords" and they were off to kill נבל.
An attendant of דוד told אביגיל what דוד was going to do. So אביגיל took 200 breads, 2 containers of wine, 5 cooked sheep, 5 se'ahs of toasted grain, 100 raisin clusters, and 200 cases of pressed figs and put them on a donkey to go meet דוד but she does not tell נבל that she brought all this food to דוד. She meets דוד and tells him that he shouldn't kill נבל because it was her fault and she convinces him not to kill him.
