There are psalms, and these are almost the most important of all, such as the 9th, the 24th and 36th Psalms, which declare the providence and the kingdom of the Living God, with that great and prophetic 2d Psalm (ver. 1- 5): "Why do the heathen so furiously rage together, and the people imagine vain things. The kings of the earth stand up, and the rulers take counsel together against the Lord, and against his anointed," &c. There are psalms of deep repentance, of the broken and the contrite heart, like that famous 51st Psalm, which is used in all Christian churches to this day, as the expression of all true repentance, and which, even in our translation, by its awful simplicity, its slow sadness, expresses in its very sound the utterly crushed and broken heart. "Have mercy upon me, O God, after thy great goodness, according to the multitude of thy mercies do away mine offences. . . . Behold, I was shapen in iniquity, and in sin did my mother conceive. . . . The sacrifice of God is a troubled spirit, a broken and a contrite heart, O God, thou wilt not despise. . . ." Then there are psalms, like the 26th, of a manful and stately confidence. The words of one who is determined to do right, who feels that on the whole he is doing it, and is not ashamed to say so. "Be thou my judge, for I have walked innocently. . . . Examine and prove me: try out my reins and my heart. I have not dwelt with vain persons, neither will I have fellowship with the deceitful. . . . I have hated the congregation of the wicked. I have loved the habitation of thy house." There are political psalms, full of weighty advice, to his sons after him, like the 115th Psalm.
