16 So he led David to them, and they found the Amalekites spread out across the fields, eating and drinking and dancing with joy because of the vast amount of plunder they had taken from the Philistines and the land of Judah. 17 David and his men rushed in among them and slaughtered them throughout that night and the entire next day until evening. None of the Amalekites escaped except 400 young men who fled on camels. 18 David got back everything the Amalekites had taken, and he rescued his two wives. 19 Nothing was missing: small or great, son or daughter, nor anything else that had been taken. David brought everything back. 20 He also recovered all the flocks and herds, and his men drove them ahead of the other livestock. "This plunder belongs to David!" they said.

21 Then David returned to the brook Besor and met up with the 200 men who had been left behind because they were too exhausted to go with him. They went out to meet David and his men, and David greeted them joyfully. 22 But some evil troublemakers among David's men said, "They didn't go with us, so they can't have any of the plunder we recovered. Give them their wives and children, and tell them to be gone." 23 But David said, "No, my brothers! Don't be selfish with what the Lord has given us. He has kept us safe and helped us defeat the band of raiders that attacked us. 24 Who will listen when you talk like this? We share and share alike-those who go to battle and those who guard the equipment." 25 From then on David made this a decree and regulation for Israel, and it is still followed today. 26 When he arrived at Ziklag, David sent part of the plunder to the elders of Judah, who were his friends. "Here is a present for you, taken from the Lord 's enemies," he said. 27 The gifts were sent to the people of the following towns David had visited: Bethel, Ramoth-negev, Jattir, 28 Aroer, Siphmoth, Eshtemoa, 29 Racal, the towns of the Jerahmeelites, the towns of the Kenites, 30 Hormah, Bor-ashan, Athach, 31 Hebron, and all the other places David and his men had visited.

Commentary on 1 Samuel 30:16-20

(Read 1 Samuel 30:16-20)

Sinners are nearest to ruin, when they cry, Peace and safety, and put the evil day far from them. Nor does any thing give our spiritual enemies more advantage than sensuality and indulgence. Eating and drinking, and dancing, have been the soft and pleasant way in which many have gone down to the congregation of the dead. The spoil was recovered, and brought off; nothing was lost, but a great deal gained.

Commentary on 1 Samuel 30:21-31

(Read 1 Samuel 30:21-31)

What God gives us, he designs we should do good with. In distributing the spoil, David was just and kind. Those are men of Belial indeed, who delight in putting hardships upon their brethren, and care not who is starved, so that they may be fed to the full. David was generous and kind to all his friends. Those who consider the Lord as the Giver of their abundance, will dispose of it with fairness and liberality.
