2 Samuel 21:17
But Abishai son of Zeruiah came to his aid, struck the Philistine, and killed him. Then David's men swore to him, "You must never again go out with us to battle, so that the lamp of Israel may not be extinguished."
But Abishai son of Zeruiah came to his aid,

Abishai was David’s nephew and one of the foremost leaders among David’s mighty men. When David grew weary in battle against the Philistines, Abishai acted with the courage and loyalty that had marked his service from earlier days. God preserved David through the faithful intervention of a kinsman and seasoned warrior.

1Sa 26:6 And David asked Ahimelech the Hittite and Abishai……
2Sa 10:11 “If the Arameans are too strong for me,” said Joab,…
2Sa 23:18 Abishai, the brother of Joab and son of Zeruiah…

struck the Philistine, and killed him.

The Philistine was Ishbi-benob, a descendant of Rapha, a family of giant warriors who continued to threaten Israel. His heavy bronze spear and new sword made David’s exhaustion especially dangerous. Abishai’s victory showed that Israel’s security did not rest upon David’s strength alone, but upon the Lord’s protection and the men raised up to serve His anointed king.

1Sa 17:50 Thus David prevailed over the Philistine with a sling…
2Sa 23:10 Eleazar stood his ground and struck the Philistines…
1Ch 20:5 Once again there was a battle with the Philistines…

Then David’s men swore to him,

David’s warriors bound themselves by a solemn oath to protect their king. Their concern arose not from diminished respect for David, but from their recognition that his life was vital to Israel’s covenantal future. David had long led Israel in battle, yet his advancing age required others to carry responsibilities he had once borne personally.

2Sa 15:21 But Ittai answered the king, “As surely as the LORD lives…
1Sa 20:16 So Jonathan made a covenant with the house of David…
2Sa 5:3 So all the elders of Israel came to the king at Hebron…

“You must never again go out with us to battle,

David’s men urged him to remain from the front lines so that he could continue to govern, guide, and strengthen the nation. The king’s death in battle could have brought instability to Israel and endangered the kingdom God had established through him.

2Sa 11:1 In the spring, at the time when kings march out to war,…
1Sa 8:20 “Then we will be like all the other nations,…

so that the lamp of Israel may not be extinguished.”

David was Israel’s lamp because God had chosen him and promised to preserve his royal house. The image of a lamp speaks of enduring life, hope, and God’s continuing presence among His people. The preservation of David’s line ultimately points to the greater Son of David, Jesus Christ, whose kingdom and light will never be extinguished.

1Ki 11:36 I will give one tribe to his son, so that My servant David…
1Ki 15:4 Nevertheless, for the sake of David, the LORD his God…
Psa 132:17 There I will make a horn grow for David;…

I. Beth-cerem, Nehemiah 3:14. "The stones, as well of the altar, as of the ascent to the altar, were from the valley of Beth-cerem, which they digged out beneath the barren land. And thence they are wont to bring whole stones, upon which the working iron came not."

"So David fled, and escaped and came to Samuel to Ramah, and told him all that Saul had done unto him. And he and Samuel went and dwelt in Naioth" (1 Sam. xix. 18)--or, as the word probably means, in the collection of students' dwellings, inhabited by the sons of the prophets, where possibly there may have been some kind of right of sanctuary. Driven thence by Saul's following him, and having had one last sorrowful hour of Jonathan's companionship--the last but one on earth--he fled to Nob, whither

Samuel
Alike from the literary and the historical point of view, the book[1] of Samuel stands midway between the book of Judges and the book of Kings. As we have already seen, the Deuteronomic book of Judges in all probability ran into Samuel and ended in ch. xii.; while the story of David, begun in Samuel, embraces the first two chapters of the first book of Kings. The book of Samuel is not very happily named, as much of it is devoted to Saul and the greater part to David; yet it is not altogether inappropriate,
