Israel, anticipating their deliverance from their enemies, celebrate the triumph of God, and call upon the nations to unite with them in praise to God.
(10:1-4) We know from Revelation, that in the days of trial, which precede the reign of Christ, a great multitude will be saved from amongst the nations. Apparently it is this great company, “the willing-hearted of the peoples” (vs. 9 JND) that are called in this psalm to express their joy with shouts of triumph, because God has vanquished every enemy. The Lord Most High has shown Himself to be terrible to those who refuse to submit to His claims. He is not only King, but “a great King” that none can withstand. He has subdued the Gentiles and exalted Israel above the nations, and, in sovereign grace has chosen the land of Israel, the excellency of Jacob whom He loved.
(vv. 5-9) The psalmist, anticipating the time when God will have taken possession of His earthly throne, calls for all to sing with intelligent praise to God, the King of all the earth, who reigns over the nations, and whose throne is characterized by holiness. Then, every opposing enemy having been subdued under the feet of Israel, the willing-hearted of the nations will be gathered together with the people of the God of Abraham, and the defense of the whole earth against all evil (the shields of the earth) will be in the hands of God: the result being that, while the whole earth will be blessed, God Himself will be greatly exalted.
