2 Sam. 21:15-22
The end of David's history has the same character as its beginning. Goliath seems to come to life again. So it was for the Lord also: after the temptation in the wilderness Satan left Him for a time and reappeared at Gethsemane, seeking to terrify Him so that He would abandon His work. His efforts were in vain and at Gethsemane as well as in the wilderness Jesus won the victory.
After Christ's victory, even though the "children of Raphah" (i.e., of the giant) attack His redeemed, thinking to overcome them more easily than their Master, their fate is the same; they come out of the strife defeated. This conflict is repeated four times with the Philistines. It is from these internal enemies that the sons of the giant proceed, these "ravening wolves" who seek to ravish the flock by frightening their leaders.
The first time David personally is involved (2 Sam. 21:15-17). He had gone down with his servants, taking neither his age nor his strength into account: "David was exhausted" (2 Sam. 21:15). Ishbibenob who was of the children of the giant, formidable with his weapon —"the weight of his lance was three hundred shekels of bronze" —invulnerable because of the "new armor" he was wearing, thinks to take advantage of the king's apparent weakness. But "Abishai the son of Zeruiah succored him, and smote the Philistine and killed him" (2 Sam. 21:17). Thus this servant of David is put to the test; he does not abandon his master in danger and has the honor of saving David. Is it not likewise with us? The Lord has fought for us and delivered us; do we not in a sense have the duty of helping Him? His name, His person, and His glory are threatened by the enemy's agents. This enemy attacks our David in order to destroy all remembrance of Him, and he knows that his time is short, for already the dawn of our Lord's glorious reign is about to break in the person of Solomon. Will the enemy succeed? We are responsible for his victory or his defeat. It is up to us now in the power of the Spirit of God to smite the giant's son, to conquer Christ's attackers, to keep His name and His word intact in face of the enemy who would destroy them.
And even if we are not "David's mighty men," should we not swear to Him as all David's servants did: "Thou shalt go no more out with us to battle, that thou quench not the lamp of Israel" (2 Sam. 21:17)? And so each one's faith is put to the test. They realize that they themselves must fight, each in his rank, so that the light of God's people might not go out but continue to shine in all its splendor. No doubt our David is never weary like the David of this history: "The everlasting God, Jehovah, the Creator of the ends of the earth, fainteth not nor tireth" (Isa. 40:28). But in order to test and strengthen our faith, to encourage our hearts in conflict and cheer them with victory and reward, He loves to place Himself in a position in relation to His own where He, the victor over Satan, seems to need our help. What a privilege to fight for Him! The time is solemn; Christ is being attacked on every hand; the enemy's effort seems formidable and surpasses our feeble resources by far. Those who ought to be with Him and defend the integrity of His Word and His Person, more often than not, alas, make common cause with the sons of the giant. Let us not be disturbed about this.
It does not matter if our David is absent as in the two battles at Gob (2 Sam. 21:18-19); the same Spirit that urged Him on is still with us. Perhaps we may be alone as Sibbechai the Hushathite was alone against Saph—for the stricken giant is always reappearing in another form. What does that matter? Perhaps — discouraging situation—Gob, the place where he was defeated, will become a battlefield for us a second time. What does it matter if we must retrace the same steps when we thought that we had finished with a treacherous struggle?
Look now! Goliath, that ancient enemy, reappears on this ground. "And there was again a battle at Gob with the Philistines, and Elhanan the son of Jaare-oregim, a Bethlehemite, smote Goliath the Gittite; now the staff of his spear was like a weaver's beam" (2 Sam. 21:19). Was not Goliath defeated by David? Be not troubled, be not afraid, Elhanan, hero of "the grace of God"! This Goliath, this Gittite, is a false Goliath bearing a deceptive name, a lying name. He is only Lahmi, Goliath's brother (cf. 1 Chron. 20:5). Yes, but he has the same spear, like a weaver's beam, doesn't he (cf. 1 Sam. 17:7)? Ask him, Elhanan, where his sword is. His sword is in David's hands and it will remain there forever. Victory is assured you, Elhanan! To win this victory there is no need even of a slingstone which you surely could never wield as deftly as your king anyway. It is confidence, the humble dependence you saw in David, that will overcome him. Yes, at any rate the victory is yours; it is ours, because it is His!
The last enemy, a monstrous intimidating man, is not named but he also was born to the giant, "a man of great stature, that had on each hand six fingers, and on each foot six toes, four and twenty in number" (2 Sam. 21:20-22). As once Goliath did, so he defies Israel (2 Sam. 21:21; 1 Sam. 17:10). In Christ's absence we must fight for Him as well as for His people. To defy the one is to defy the other. We have brothers who are captives of the enemy, like Lot, sadly linked up with the world as he was, who must be saved "with fear, snatching them out of the fire" (Jude 23). Let us stand in the breach like Jonathan the son of Shimeah and let us demonstrate that like him by grace we bear the name "David's brothers" (cf. 2 Sam. 21:21). Like him may we have the interests of His people at heart.
How painful it is to hear: Why are you meddling? We are all right where we are. You are making war against us—for they identify themselves with the enemy enslaving them and prefer their slavery to the liberty which is offered to them. But what of it? Let us fight for them, let us smite this terrible power that defies God's people. Another blow, this one will be the last. Just one more victory and the Lord will deliver us from the hand of all our enemies, and we shall in peace be able to raise the words of our song to Him, as did David!
