Psalms 47:1

Just as there is wailing by all the nations in the coming of the devil as we have heard the voice calling from heaven, "woe to land and sea, for the devil has been cast on you," so in the coming of our Jesus, there …

"O clap your hands, all ye nations." Were the people of the Jews all the nations? No, but blindness in part is happened to Israel, that senseless children might cry, "Calve," "Calve;" and so the Lord might be crucified in the place of Calvary, that by His Blood shed He might redeem the Gentiles, and that might be fulfilled which saith the Apostle, "Blindness in part is happened unto Israel, until the fulness of the Gentiles be come in." Let them insult, then, the vain, and foolish, and senseless, and say, "Calve," "Calve;" but ye redeemed by His Blood which was shed in the place of Calvary, say, "O clap your hands, all ye nations;" because to you hath come down the Grace of God. "O clap your hands." What is "O clap"? Rejoice. But wherefore with the hands? Because with good works. Do not rejoice with the mouth while idle with the hands. If ye rejoice, "clap your hands." The hands of the nations let Him see, who joys hath deigned to give them. What is, the hands of the nations? The acts of them doing good works. "O clap your hands, all ye nations; shout unto God with the voice of triumph." Both with voice and with hands. If with the voice only it is not well, because the hands are slow; if only with the hands it is not well, because the tongue is mute. Agree together must the hands and tongue. Let this confess, these work. "Shout unto God with the voice of triumph."

With hands that were previously defiled, accursed, daily stained with blood in the impure sacrifices in which you took the lives of your children, performed shameful rites and went beyond the limits of nature itself, with these hands now clap. "Shout to God in a voice of happiness." With that tongue by which you tasted accursed things, by which you uttered blasphemous words, with that tongue shout a victory ode.… You have mounted above heavens and the heavens of heavens and have taken your place at the royal throne itself. Accordingly, "Shout to God," that is, offer thanksgiving to him, the victory to him, the trophy to him. The conflict is not human or the battle physical, nor is the contest over any earthly concern but over the heavens and those in the heavens. He personally conducted this war and gave us a share in the victory.

In the preceding Psalms the Psalmist expounded the glory of the King and of the kingdom; here he exhorts the foreign nations to be converted to God. And first he exhorts them to the praise of God. Second, to hope in God. Third, he teaches …

O clap your hands. The most natural and most enthusiastic tokens of exultation are to be used in view of the victories of the Lord, and his universal reign. Our joy in God may be demonstrative, and yet he will not censure it. All ye people. The joy is to extend to all nations; Israel may lead the van, but all the Gentiles are to follow in the march of triumph, for they have an equal share in that kingdom where there is neither Greek nor Jew, but Christ is all and in all.
