John Calvin Commentary Psalms 34:3

"Oh magnify Jehovah with me, And let us exalt his name together." — Psalms 34:3 (ASV)

Magnify Jehovah with me. The Psalmist shows yet another fruit that would result from his giving thanks to God: specifically, that he will encourage others by his example to the same practice of devotion. Even more, he calls on all the godly to unite with him in this practice, inviting and exhorting them to extol the Lord wholeheartedly and with one accord.

Therefore, let us learn from the many instances in which God may have helped any of His people, to abound in hope. And when each one recounts the personal benefits he has received, let all be inspired to unite in publicly praising God.

We give thanks to God publicly, not only so that people may be witnesses of our gratitude, but also so that they may follow our example.
