Commentary on Psalms Volume 2 John Calvin
JOHN CALVIN
Hebrews often use this form of expression when the name of any man is used as an example or formula of prayer for blessings. For instance, a man blesses himself in David, who beseeches God to be as favorable and bountiful to him as he proved himself to be towards David. On the other hand, he is said to curse in Sodom and Gomorrah who employs the names of these cities by which to pronounce some curse. If, then, these two expressions, they shall bless themselves in him, and they shall call him blessed, are used in the same sense; the expression, to bless themselves in the king, will just mean to pray that the same prosperity may be conferred upon us which was conferred upon this highly favored king, whose happy condition will excite universal admiration. But if it is considered preferable to distinguish between these two expressions, (which is not less probable,) to bless one's self in the king, will denote to seek happiness from him; for the nations will be convinced that nothing is more desirable than to receive from him laws and ordinances.
18. Blessed be Jehovah God! the God of Israel. 628 David, after having prayed for prosperity to his successors, breaks forth in praising God, because he was assured by the divine oracle that his prayers would not be in vain. Had he not with the eyes of faith beheld those things which we have seen above, his rejoicing would have been less free and lively. When he says that God alone doeth wonderful things, this, no doubt, is spoken in reference to the subject of which he is presently treating, with the view not only of commending the excellence of the kingdom, but also to admonish himself and others of the need which there is that God should display his wonderful and stupendous power for its preservation. And certainly it was not owing to any of David's successors, a few excepted, that the royal throne did not fall a hundred times, yea, was not even completely ruined. To go no farther, was not Solomon's most disgraceful apostasy deserving of utter destruction? And as to the rest of his successors, with the exception of Josias, Hezekiah, Jehoshaphat, and a few others, did they not fall from evil to worse, as if each strove to outstrip his predecessor, and thus so provoked the wrath of God, as it were deliberately, that it is wonderful that he did not immediately launch the thunderbolts of his vengeance upon the whole race utterly to destroy them? Moreover, as David, being endued with the Spirit of prophecy, was not ignorant that Satan would always continue to be a cruel enemy of the Church's welfare, he doubtless knew that the grace of God, of which he presently speaks, would have great and arduous difficulties to overcome in order to continue for ever in his own nation. And the event afterwards unquestionably showed by how many miracles God accomplished his promises, whether we consider the return of his people from the captivity
This psalm concludes the second book of the Psalms, and this and the following verse are a doxology similar to that with which the first book and the other three are concluded. See volume 2, p. 126, note.
