Psalms 34:3

O magnify the Lord with me - This seems to be addressed primarily to the “humble,” those referred to in the previous verse. As they could appreciate what he would say, as they could understand the nature of his feelings in view of his deliverance, he calls upon them especially to exult with him in the goodness of God. As he and they had common calamities and trials, so might they have common joys; as they were united in danger and sorrow, so it was proper that they should be united in joy and in praise. The word “magnify’ means literally “to make great,” and then, to make great in the view of the mind, or to regard and treat as great. The idea is, that he wished all, in circumstances similar to those in which he had been placed, to have a just sense of the greatness of God, and of his claims to love and praise. Compare Psalms 35:27; Psalms 40:17; Psalms 69:30; Psalms 70:4; Luke 1:46.

And let us exalt his name together - Let us unite in “lifting up” his name; that is, in raising it above all other things in our own estimation, and in the view of our fellow-men; in so making it known that it shall rise above every other object, that all may see and adore.
