The universal and perpetual diffusion of the kingdom and knowledge of God is the theme of the closing strain (vv. 27-31). That diffusion is not definitely stated as the issue of the sufferings or deliverance, but the very fact that such a universal knowledge comes into view here requires that it should be so regarded, else the unity of the psalm is shattered. While, therefore, the ground alleged in ver. 28 for this universal recognition of God is only His universal dominion, we must suppose that the history of the singer as told to the world is the great fact which brings home to men the truth of God's government over and care for them. True, men know God apart from revelation and from the gospel, but He is to them a forgotten God, and the great influence which helps them to "remember and turn to Jehovah" is the message of the Cross and the Throne of Jesus. The psalm had just laid down the condition of partaking in the sacrificial meal as being lowliness, and (ver. 29) it prophecies that the "fat" shall also share in it. That can only be, if they become "humble." Great and small, lofty and low must take the same place and accept the food of their souls as a meal of charity. The following words are very difficult, as the text stands. There would appear to be a contrast intended between the obese self-complacency of the prosperous and proud, and the pauper-like misery of "those who are going down to the dust" and who "cannot keep their soul alive," that is, who are in such penury and wretchedness that they are all but dead. There is a place for ragged outcasts at the table side by side with the "fat on earth." Others take the words as referring to those already dead, and see here a hint that the dim regions of Sheol receive beams of the great light and some share in the great feast. The thought is beautiful, but too remote from anything else in the Old Testament to be adopted here. Various attempts at conjectural emendations and redivision of clauses have been made in order to lighten the difficulties of the verse. However attractive some of these are, the existing reading yields a not unworthy sense, and is best adhered to.
