Charles H. Spurgeon on Psalms 138:2

Thou hast magnified thy word above all thy name. Thou hast bestowed the promise of perpetuity to my house and to my kingdom, which rises in grandeur and goodness above all thy past manifestations of thyself in behalf of thy people (2Sa 7:10 12-13 15-16 7:21-22 2Sa 24-26 29; 2Sa 7:21 especially, "For thy Word's sake ...hast thou done all these great things"; 2Sa 7:26, "And let thy name be magnified for ever" —an undesigned coincidence of language between the history and the Psalm). In the Messiah alone the greatness of the promise finds, and shall hereafter more fully find, its realization for Israel and the whole world. —Andrew Robert Fausset.
