Psalms 67:5

the people As before, the peoples. This refrain is generally treated as before as a wish or prayer; but it is worth considering whether the tone of the last stanza does not change throughout from prayer to confident hope, so that we should render, The peoples shall give thanks unto thee, O God.The form of a refrain is often slightly varied, why not its tone? The ambiguity arises from the fact that Heb. (with some exceptions) does not possess separate forms for the future and the optative.
