This new song is saturated with reminiscences of old ones, and deals with familiar thoughts which have come to the psalmist with fresh power. He magnifies the moral attributes manifested in God's self-revelation, His creative Word, and His providential government. "The word of Jehovah," in ver. 4, is to be taken in the wide sense of every utterance of His thought or will ("non accipi pro doctrina, sed pro mundi gubernandi ratione," Calvin). It underlies His "works," as is more largely declared in the following verses. It is "upright," the same word as in ver. 1, and here equivalent to the general idea of morally perfect. The acts which flow from it are "in faithfulness," correspond to and keep His word. The perfect word and works have for source the deep heart of Jehovah, which loves "righteousness and judgment," and therefore speaks and acts in accordance with these. Therefore the outcome of all is a world full of God's loving-kindness. The psalmist has won that "serene and blessed mood" in which the problem of life seems easy, and all harsh and gloomy thoughts have melted out of the sky. There is but one omnipotent Will at work everywhere, and that is a Will whose law for itself is the love of righteousness and truth. The majestic simplicity and universality of the cause are answered by the simplicity and universality of the result, the flooding of the whole world with blessing. Many another psalm shows how hard it is to maintain such a faith in the face of the terrible miseries of men, and the more complex "civilisation" becomes, the harder it grows; but it is well to hear sometimes the one clear note of gladness without its chord of melancholy.
