Here, I. The Philistines invade Israel (Sa1 7:7), taking umbrage from that general meeting for repentance and prayer as if it had been a rendezvous for war, and, if so, they thought it prudent to keep the war out of their own country. They had no just cause for this suspicion; but those that seek to do mischief to others will be forward to imagine that others design mischief to them. Now see here, 1. How evil sometimes seems to come out of good. The religious meeting of the Israelites at Mizpeh brought trouble upon them from the Philistines, which perhaps tempted them to wish they had staid at home and to blame Samuel for calling them together. But we may be in God's way and yet meet with distress; nay, when sinners begin to repent and reform, they must expect that Satan will muster all his force against them, and set his instruments on work to the utmost to oppose and discourage them. But, 2. How good is, at length, brought out of that evil. Israel could never be threatened more seasonably than at this time, when they were repenting and praying, nor could they have been better prepared to receive the enemy; nor could the Philistines have acted more impolitely for themselves than to make war upon Israel at this time, when they were making their peace with God. But God permitted them to do it, that he might have an opportunity immediately of crowning his people's reformation with tokens of his favour, and of confirming the words of his messenger, who had assured them that if they repented God would deliver them out of the hand of the Philistines. Thus he makes man's wrath to praise him, and serves the purposes of his grace to his people even by the malicious designs of their enemies against them, Mic 4:11, Mic 4:12. II. Israel cleaves closely to Samuel, as their best friend, under God, in this distress; though he was no military man, nor ever celebrated as a mighty man of valour, yet, being afraid of the Philistines, for whom they thought themselves an unequal match, they engaged Samuel's prayers for them: Cease not to cry unto the Lord our God for us, Sa1 7:8. They were here unarmed, unprepared for war, come together to fast and pray, not to fight; prayers and tears therefore being all the weapons many of them are now furnished with, to these they have recourse. And, knowing Samuel to have a great interest in heaven, they earnestly beg of him to improve it for them. They had reason to expect it, because he had promised to pray for them (Sa1 7:5), had promised them deliverance from the Philistines (Sa1 7:3), and they had been observant of him in all that which he had spoken to them from the Lord. Thus those who sincerely submit to Christ, as their lawgiver and judge, need not doubt of their interest in his intercession. They were very solicitous that Samuel should not cease to pray for them: what military preparations were to be made they would undertake them, but let him continue instant in prayer, perhaps remembering that when Moses did but let down his hand ever so little Amalek prevailed. O what a comfort is it to all believers that our great intercessor above never ceases, is never silent, for he always appears in the presence of God for us! III. Samuel intercedes with God for them, and does it by sacrifice, Sa1 7:9. He took a sucking lamb, and offered it for a burnt-offering, a whole burnt-offering, to the Lord, and, while the sacrifice was in burning, with the smoke of it his prayers ascended up to heaven for Israel. Observe, 1. He made intercession with a sacrifice. Christ intercedes in the virtue of his satisfaction, and in all our prayers we must have an eye to his great oblation, depending upon that for audience and acceptance. Samuel's sacrifice without his prayer would have been an empty shadow, his prayer without the sacrifice would not have been so prevalent, but both together teach us what great things we may expect from God in answer to those prayers which are made with faith in Christ's sacrifice. 2. It was a burnt-offering, which was offered purely for the glory of God, so intimating that the great plea he relied on in his prayer was taken from the honour of God. "Lord, help thy people now for thy name's sake." When we endeavour to give glory to God we may hope he will, in answer to our prayers, work for his own glory. 3. It was but one sucking lamb that he offered; for it is the integrity and intention of the heart that God looks at, more than the bulk or number of the offerings. This one lamb (typifying the Lamb of God) was more acceptable than thousands of rams or bullocks would have been without faith and prayer. Samuel was no priest, but he was a Levite and a prophet; the case was extraordinary, and what he did was by special direction, and therefore was accepted of God. And justly was this reproach put upon the priests because they had corrupted themselves. IV. God gave a gracious answer to Samuel's prayer (Sa1 7:9): The Lord heard him. He was himself a Samuel, asked of God, and many a Samuel, many a mercy in answer to prayer, God gave him. Sons of prayer should be famous for praying, as Samuel was among those that call upon his name, Psa 99:6. The answer was a real answer: the Philistines were discomfited (Sa1 7:10, Sa1 7:11), totally routed, and that in such a manner as highly magnified the prayer of Samuel, the power of God, and the valour of Israel. 1. The prayer of Samuel was honoured; for at the very time when he was offering up his sacrifice, and his prayer with it, the battle began, and turned immediately against the Philistines. Thus while he was yet speaking God heard, and answered in thunder, Isa 65:24. God showed that it was Samuel's prayer and sacrifice that he had respect to, and hereby let Israel know that as in a former engagement with the Philistines he had justly chastised their presumptuous confidence in the presence of the ark, on the shoulders of two profane priests, so now he graciously accepted their humble dependence upon the prayer of faith from the mouth and heart of a pious prophet. 2. The power of God was greatly honoured; for he took the work into his own hand, and discomfited them, not with great hail-stones, which would kill them (as Jos 10:11), but with a great thunder, which frightened them and put them into such terror and consternation that they fainted away, and became a very easy prey to the sword of Israel, before whom, being thus confounded, they were smitten. Josephus adds that the earth quaked under them when first they made the onset and in many places opened and swallowed them up, and that, besides the terror of the thunder, their faces and hands were burnt with lightning, which obliged them to shift for themselves by flight. And, being thus driven to their heels by the immediate hand of God (whom they feared not so much as they had feared his ark, Sa1 4:7), then, 3. Honour was put upon the hosts of Israel; they were made use of for the completing of the victory, and had the pleasure of triumphing over their oppressors: They pursued the Philistines, and smote them. How soon did they find the benefit of their repentance, and reformation, and return to God! Now that they have thus engaged him for them none of their enemies can stand before them. V. Samuel erected a thankful memorial of this victory, to the glory of God and for the encouragement of Israel, Sa1 7:12. He set up an Eben-ezer, the stone of help. If ever the people's hard hearts should lose the impressions of this providence, this stone would either revive the remembrance of it, and make them thankful, or remain a standing witness against them for their unthankfulness. 1. The place where this memorial was set up was the same where, twenty years before, the Israelites were smitten before the Philistines, for that was beside Eben-ezer, Sa1 4:1. The sin which procured that defeat formerly being pardoned upon their repentance, the pardon was sealed by this glorious victory in the very same place where they then suffered loss; see Hos 1:10. 2. Samuel himself took care to set up this monument. He had been instrumental by prayer to obtain the mercy, and therefore he thought himself in a special manner obliged to make this grateful acknowledgement of it. 3. The reason he gives for the name is, Hitherto the Lord hath helped us, in which he speaks thankfully of what was past, giving the glory of the victory to God only, who had added this to all his former favours; and yet he speaks somewhat doubtfully for the future: "Hitherto things have done well, but what God may yet do with us we know not, that we refer to him; but let us praise him for what he has done." Note, The beginnings of mercy and deliverance are to be acknowledged by us with thankfulness so far as they go, though they be not completely finished, nay, though the issue seem uncertain. Having obtained help from God, I continue hitherto, says blessed Paul, Act 26:22.
