Psalms 132:2

For what purpose? "How he sware unto the Lord, and vowed a vow unto the Almighty God of Jacob" (ver. 2). Therefore remember for this, that he may fulfil what he hath promised. David himself vowed as though he had it in his power, and he prayeth God to fulfil his vow: there is devotion in the vow, but there is humility in the prayer. Let no one presume to think he fulfilled by his own strength what he hath vowed. He who exhorteth thee to vow, Himself aideth thee to fulfil. Let us therefore see what he vowed, and hence we comprehend how David should be understood in a figure. "David" is interpreted, "Strong of hand," for he was a great warrior. Trusting indeed in the Lord his God, he despatched all wars, he laid low all his enemies, God helping him, according to the dispensation of that kingdom; prefiguring nevertheless some One strong of hand to destroy His enemies, the devil and his angels. These enemies the Church warreth against, and conquereth. ...

How he sware unto the Lord, and vowed unto the mighty God of Jacob.

How he sware unto the Lord, and vowed unto the mighty God of Jacob. Moved by intense devotion, David expressed his resolve in the form of a solemn vow, which was sealed with an oath. The fewer of such vows the better under a dispensation whose great Representative has said, "swear not at all." Perhaps even in this case it had been wiser to have left the pious resolve in the hands of God in the form of a prayer; for the vow was not actually fulfilled as intended, since the Lord forbade David to build him a temple.

This vow is not elsewhere recorded. It expresses, in strong language, David's intense desire to see the establishment of God's worship as well as of His kingdom. remember David--literally, "remember for David," that is, all his troubles and anxieties on the matter.

We had better not swear to do anything before we know the Lord's mind about it, and then we shall not need to swear. The instance of David's vows shows that vows are allowable, but it does not prove that they are desirable. Probably David went too far in his words, and it is well that the Lord did not hold him to the letter of his bond, but accepted the will for the deed, and the meaning of his promise instead of the literal sense of it. David imitated Jacob, that great maker of vows at Bethel, and upon him rested the blessing pronounced on Jacob by Isaac, "God Almighty bless thee" (Ge 28:3), which was remembered by the patriarch on his death bed, when he spoke of "the mighty God of Jacob." God is mighty to hear us, and to help us in performing our vow. We should be full of awe at the idea of making any promise to the Mighty God: to dare to trifle with him would be grievous indeed. It is observable that affliction led both David and Jacob into covenant dealings with the Lord: many vows are made in anguish of soul. We may also remark that, if the votive obligations of David are to be remembered of the Lord, much more are the suretyship engagements of the Lord Jesus before the mind of the great Lord, to whom our soul turns in the hour of our distress.
