Psalms 111:7

"The works of his hands are truth and justice;

And his precepts are sure.

They are established forever and ever;

They are done in truth and uprightness."

"The reference in these two verses is the giving of the law at Sinai."[14]

"Forever and ever" (Psalms 111:8). This is a reference to all time until the Christ should come. And, in the truth that Christ's righteousness consisted, among other things, in the absolute and perfect fulfilment of that Law given at Sinai; and, since the righteousness of Christ is the grounds of salvation for all men for all ages to come, there is a sense in which the words are strictly true as a reference to all time until the end of time.
