Psalms 33:21

21. Surely our heart shall rejoice in him. As the particle כי, ki, which is twice employed in this verse, has various meanings in Hebrew, it may be understood in a twofold sense here. If we expound it affirmatively in both clauses, the sense will be, that believers glory both in their joy and in their hope. Nor do I think it improper that these two should be referred to distinctly in the same context thus: Surely God shall always be our joy; surely his holy name shall be like an impregnable fortress for our refuge. Whence is it that believers continue perseveringly to call upon God, but because, satisfied with his favor, they have always, amidst their sorrows and griefs, this comfort, which is sufficient to maintain their cheerfulness? Justly, therefore, do believers affirm, in the first place, that their heart rejoices in the Lord; because, freed from wandering after the fascinations of the world, they neither waver nor hesitate at every change of fortune, but place the whole felicity of their life in enjoying the free and paternal favor of God. They afterwards add, in the second place, that they trust in his holy name. If any one, however, choose to understand the particle כי, ki, as meaning because, assigning a cause or reason, the sense will be no less properly and elegantly expressed in this way: Because our hope is fixed on God, he will be equally ready on his part to minister to us continual matter of joy. And experience undoubtedly proves, that when men are overwhelmed with sorrow, and pine away with care, grief, and anxiety, it is that they may receive the recompense of their folly; seeing that there is nothing to which they are led with more difficulty, than to set their hopes on God alone, and not to exult in their own deceitful imaginations, with which they please themselves.
