Psalms 65:2 - Ellicott's Commentary On The Whole Bible

Unto thee shall all flesh come. — This has usually, and most truly, been taken as prophetic of the extension of the true religion to the Gentiles. But we must not let what was, in the Divine providence, a fulfilment of the psalmist’s words, hide their intention as it was conscious to himself. The psalm shows us the exclusiveness of Hebrew belief, and, at the same time, the nobler and grander feelings which are from time to time found struggling against it. The peculiar privilege of Israel has been stated in the first verse. Silent, yet confident, waiting for Jehovah’s blessing, and then exultant praise for it (Tehillah). In this the other nations have no part; but all flesh may approach Jehovah in prayer (Tephillah). (Compare Psalms 65:5.)
