The psalmist has done with the enemies; they are at the bottom of the pit. In full confidence of triumph and deliverance, he breaks out into a grand burst of praise. "My heart is fixed," or "steadfast." Twice the psalmist repeats this, as he does other emphatic thoughts, in this psalm (_cp._ vv. 2, 4, 8, 9). What power can steady that fluttering, wayward, agitated thing, a human heart? The way to keep light articles fixed on deck, amidst rolling seas and howling winds, is to lash them to something fixed; and the way to steady a heart is to bind it to God. Built into the Rock, the building partakes of the steadfastness of its foundation. Knit to God, a heart is firm. The psalmist's was steadfast because it had taken refuge in God; and so, even before his rescue from his enemies came to pass, he was emancipated from the fear of them, and could lift this song of praise. He had said that he must lie down among lions. But wherever his bed may be, he is sure that he will rise from it; and however dark the night, he is sure that a morning will come. In a bold and beautiful figure he says that he will "wake the dawn" with his song. The world-wide destination of his praise is clear to him. It is plain that such anticipations as those of ver. 9 surpass the ordinary poetic consciousness, and must be accounted for on some special ground. The favourite explanation at present is that the singer is Israel, conscious of its mission. The old explanation that the singer is a king, conscious of his inspiration and divinely given office, equally meets the case. The psalmist had declared his trust that God would send out His angels of Loving-kindness and Troth. He ends his song with the conviction, which has become to him matter of experience, that these Divine "attributes" tower to heaven, and in their height symbolise their own infinitude. Nor is the other truth suggested by ver. 10 to be passed over, that the manifestation of these attributes on earth leads to their being more gloriously visible in heaven. These two angels, who come forth from on high to do God's errands for His poor, trusting servant, go back, their work done, and are hailed as victors by the celestial inhabitants. By God's manifestation of these attributes to a man, His glory is exalted above the heavens and all the earth. The same thought is more definitely expressed in Paul's declaration that "to the principalities and powers in heavenly places is known by the Church the manifold wisdom of God." PSALM LVIII.
