Albert Barnes Commentary Psalms 79:13

"So we thy people and sheep of thy pasture Will give thee thanks for ever: We will show forth thy praise to all generations." — Psalms 79:13 (ASV)

So we thy people, and sheep of thy pasture - See the notes at Psalms 74:1.

Will give thee thanks for ever - We will praise you always; we will acknowledge you as our God and will forevermore offer you thanksgiving.

We will shew forth thy praise to all generations - Margin, as in Hebrew, "to generation and generation." That is, we will make arrangements so that the memory of these gracious acts will be transmitted to future times and to distant generations.

This was accomplished by the permanent record, made in the Scriptures, of God's gracious interventions, and by these records being carefully preserved by each generation that received them. No work has been more faithfully done than that of preserving the records of God’s ancient dealings with His people from age to age—the work by which the sacred Scriptures have been guarded against error and handed down from one generation to another.
