Albert Barnes Commentary Psalms 78:4

"We will not hide them from their children, Telling to the generation to come the praises of Jehovah, And his strength, and his wondrous works that he hath done." — Psalms 78:4 (ASV)

We will not hide them from their children - From their descendants, however remote. We of this generation will be faithful in handing down these truths to future times. We stand between past generations and the generations to come. We are entrusted by those who have gone before us with great and important truths—truths to be preserved and transmitted in their purity to future ages.

That trust committed to us we will faithfully discharge. These truths shall not suffer in passing from us to them. They shall not be hindered in their progress; they shall not be corrupted or impaired.

This is the duty of each successive generation in the world. Each generation receives, as a trust from past generations, the result of their thoughts, their experience, their wisdom, their inventions, their arts, their sciences, and the records of their deeds. Their duty is to hand these down unimpaired to future ages, combined with all that they themselves may invent or discover that may be useful or advantageous to the generations following.

Showing to the generation to come the praises of the Lord - The reasons why he should be praised, as resulting from his past deeds—and the ways in which it should be done. We will maintain and transmit to future times the pure institutions of religion.

And his strength - The records of his power.

And his wonderful works that he has done - In the history of his people, and in his many and varied interpositions on their behalf.
