Verses 1–8
Second Samuel - Chapter 18
Battle Plans, vs. 1-8
When time came for the ultimate decision in battle, who should be king of Israel, David was in much better condition than when he fled from Jerusalem. The length of time involved in between could have been a few weeks to several months. The Scriptures give no clear indication, but it was sufficient for the loyal subjects of David to rally to him. Whereas he left Jerusalem with a few hundred men he could now muster thousands, as indicated by verse one. There had also been time sufficient to organize the forces under captains. There were three contingents in the army, the first under Joab the supreme captain of the host, another under Abishai captain of the mighty men, and the third under Ittai captain of the Gittites. All these men were extremely loyal and faithful to David.
David proposed to go himself to battle with them, but his men would not allow it. They knew he was the one for whom Absalom’s forces would seek, to slay him. If they could dispose of David there would be no further cause for his men to fight, and Absalom would be in line for the throne as the oldest surviving son. So the people concluded that the king was of more worth in the cause than ten thousand men. He should remain in the city and send them aid as needed.
David agreed to abide by the wishes of the people. He stood beside the gate to exhort and review the troops as they went forth to the battle. He gave express command to the three chief captains that they should deal gently with Absalom for his sake. After all that unworthy son had done to his father David was still willing to show him mercy. He did not want him to die, likely because he knew Absalom’s heart was not right with God. David surely fulfills the beatitude of the Lord, "Blessed are the merciful, for they shall obtain mercy" (Matthew 5:7). All the men heard David give command concerning Absalom to the captains, a significant point in the sequel.
The battle site was the wood, or the forest; of Ephraim. There has been some speculation concerning this place. Back in chapter 2 Samuel 17:26 it is clearly stated that Absalom brought the army of Israel across the Jordan into the land of Gilead and set up camp there. It has been conjectured that the contest between the Israelite army and the army of David may have consisted of a number of skirmished to and fro across the Jordan valley and river, so that the final battle may have occurred on the west side in the tribe of Ephraim, hence the name of the forest. Others with seemingly more logic have suggested that the wood of Ephraim was the site of the battle between the Ephraimites and the men of Jephthah, in Gilead, in the days of the judges (Judges 12:1-7).
The army of Israel under Amasa and Absalom could not withstand the superbly trained men of David, and they soon fell before them. Twenty thousand lost their lives as the battle raged through the forest and over the country side. It is stated that more were lost in the wilds of the forest than died in actual battle.
