Psalms 74:18

Remember this, that the enemy hath reproached - Has used opprobrious and abusive words in regard to thee, and to thy people. The idea is, that religion - the true religion - had been reproached by the foe. They had treated that religion as if it were false; they had reproached God as if he were a false God, and as if he were unable to defend his people. Compare Isaiah 36:4, Isaiah 36:13; Isaiah 37:10, Isaiah 37:23. The prayer here is, that God would remember that these words of reproach were against himself, and that he would regard them as such.

And that the foolish people have blasphemed thy name - Have blasphemed thee - the name often being put for the person himself. The word “foolish” here may refer to them as “wicked” as well as foolish. Wickedness and folly are so connected - they are so commonly combined, that the word may be used to describe the enemies of God in either sense - characterising their conduct as either the one or the other.
