The third strophe comes still closer to the particular deliverance underlying the psalm. Why should all "peoples" be called upon to praise God for it? The psalmist has learned that Israel's history is meant to teach the world what God is, and how blessed it is to dwell under His wing. No exclusiveness taints his enjoyment of special national privileges. He has reached a height far above the conceptions of the rest of the world in his day, and even in this day, except where the Christian conception of "humanity" has been heartily accepted. Whence came this width of view, this purifying from particularism, this anticipation by so many centuries of a thought imperfectly realised even now? Surely a man who in those days and with that environment could soar so high must have been lifted by something mightier than his own spirit. The details of the Divine dealings described in the strophe are of small consequence in comparison with its fixed expectation of the world's participation in Israel's blessings. The familiar figures for affliction reappear--namely, proving and refining in a furnace. A less common metaphor is that of being prisoned in a _dungeon_, as the word rendered "net" in the A.V. and R.V. probably means. Another peculiar image is that of ver. 12: "Thou hast caused men to ride over our head." The word for "men" here connotes feebleness and frailty, characteristics which make tyranny more intolerable; and the somewhat harsh metaphor is best explained as setting forth insolent and crushing domination, whether the picture intended is that of ruthless conquerors driving their chariots over their prone victims, or that of their sitting as an incubus on their shoulders and making them like beasts of burden. Fire and water are standing figures for affliction. With great force these accumulated symbols of oppression are confronted by one abrupt clause ending the strophe, and describing in a breath the perfect deliverance which sweeps them all away: "Thou broughtest us out into abundance." There is no need for the textual alteration of the last word into "a wide place" (Hupfeld), a place of liberty (Cheyne), or freedom (Baethgen). The word in the received text is that employed in Psalm xxiii. 5. "My cup is _overfulness_" and "abundance" yields a satisfactory meaning here, though not closely corresponding to any of the preceding metaphors for affliction.
The fourth strophe (vv. 13-15) begins the solo part. It clothes in a garb appropriate to a sacrificial system the thought expressed in more spiritual dress in the next strophe, that God's deliverance should evoke men's praise. The abundance and variety of sacrifices named, and the fact that "rams" were not used for the offerings of individuals, seem to suggest that the speaker is, in some sense, representing the nation, and it has been supposed that he may be the high priest. But this is merely conjecture, and the explanation may be that there is a certain ideal and poetical tone over the representation, which does not confine itself to scrupulous accuracy.
The last strophe (vv. 16-20) passes beyond sacrificial symbols, and gives the purest utterance to the emotions and resolves which ought to well up in a devout soul on occasion of God's goodness. Not only does the psalmist teach us how each individual must take the general blessing for his very own--of which act the faith which takes the world's Christ for my Christ is the supreme example--but he teaches us that the obligation laid on all recipients of God's mercy is to tell it forth, and that the impulse is as certain to follow real reception as the command is imperative. Just as Israel received deliverances that the whole earth might learn how strong and gracious was Israel's God, we receive His blessings, and chiefly His highest gift of life in Christ, not only that we may live, but that, living, we may "declare the works of the Lord." He has little possession of God's grace who has not felt the necessity of speech, and the impossibility of the lips being locked when the heart is full.
