Charles H. Spurgeon on Psalms 132:10

For thy servant David's sake. Solomon's plea for the divine blessing to rest upon him as king, "For thy servant David's sake", was justified in its use by God: Isa 37:35. It gives no countenance to the idea of intercession on the part of deceased saints; for it is not a prayer to David, but a pleading with God for the sake of David. Nor does it support the idea of works of supererogation on the part of David; it only implies a special divine delight in David, on account of which God was pleased to honour David's name during succeeding generations; and if the delight itself is pure grace, the expression of it, in any way, must be grace. Nor does it even give countenance to the idea that God's converting and saving grace may be expected by any man because his parents or ancestors were delighted in by God; for a plea of this character is in Scripture strictly confined to two instances, Abraham and David, with both of whom a special covenant was made, including their descendants, and it was just this covenant that authorised the use of the plea by those who by promise were specially interested, and by none others, and for the ends contemplated by the covenant. But it did prefigure the great Christian plea, "For Christ Jesus' sake"; just as God's selection of individual men and making them centres of revelation and religion, in the old time; prefigured "The man Christ Jesus" as the centre and basis of religion for all time. Hence in the plea, "For Christ's sake", the old pleas referred to are abolished, as the Jewish ritual is abolished. Christ bids us use His name: Joh 16:13-14,20, etc. To believe the false notions mentioned above, or to trust in any other name for divine, gracious favour, is to dishonour the name of Christ. "For Christ's sake" is effective on account of the great covenant, the merits of Christ, and his session in heaven. —John Field (of Sevenoaks), 1883.
