16 When he had taken him down, they were spread out all over the ground, eating and drinking and dancing, because of the great amount of spoil they had taken from the land of the Philistines and from the land of Judah. 17 David attacked them from twilight until the evening of the next day. Not one of them escaped, except four hundred young men, who mounted camels and fled. 18 David recovered all that the Amalekites had taken; and David rescued his two wives. 19 Nothing was missing, whether small or great, sons or daughters, spoil or anything that had been taken; David brought back everything. 20 David also captured all the flocks and herds, which were driven ahead of the other cattle; people said, "This is David's spoil."

21 Then David came to the two hundred men who had been too exhausted to follow David, and who had been left at the Wadi Besor. They went out to meet David and to meet the people who were with him. When David drew near to the people he saluted them. 22 Then all the corrupt and worthless fellows among the men who had gone with David said, "Because they did not go with us, we will not give them any of the spoil that we have recovered, except that each man may take his wife and children, and leave." 23 But David said, "You shall not do so, my brothers, with what the Lord has given us; he has preserved us and handed over to us the raiding party that attacked us. 24 Who would listen to you in this matter? For the share of the one who goes down into the battle shall be the same as the share of the one who stays by the baggage; they shall share alike." 25 From that day forward he made it a statute and an ordinance for Israel; it continues to the present day. 26 When David came to Ziklag, he sent part of the spoil to his friends, the elders of Judah, saying, "Here is a present for you from the spoil of the enemies of the Lord"; 27 it was for those in Bethel, in Ramoth of the Negeb, in Jattir, 28 in Aroer, in Siphmoth, in Eshtemoa, 29 in Racal, in the towns of the Jerahmeelites, in the towns of the Kenites, 30 in Hormah, in Bor-ashan, in Athach, 31 in Hebron, all the places where David and his men had roamed.

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.
