18 But I say, surely they have never heard, have they? Indeed they have; “Their voice has gone out into all the earth, and their words to the ends of the world.” 19 But I say, surely Israel did not know, did they? First Moses says, “I will make you jealous by that which is not a nation, by a nation without understanding will I anger you” (Romans 10).
The quote in verse 18 is from Psalm 19: “1 The heavens are telling of the glory of God; and their expanse is declaring the work of His hands. 2 Day to day pours forth speech, and night to night reveals knowledge. 3 There is no speech, nor are there words; their voice is not heard.” The quote in verse 19 is from Deuteronomy 32:21: “They have made Me jealous with what is not God; they have provoked Me to anger with their idols. So I will make them jealous with those who are not a people; I will provoke them to anger with a foolish nation.”
Paul is shaming the Jews by grouping them among the Gentiles, for all Jews have the same opportunity as the Gentiles to hear the heavens telling of God and to be drawn to Him. And yet, the Gentiles (who are “not a people” and just “a foolish nation”) are indeed drawn to God with the Gospel, while the Jews are not.
In the end, the lesson is this: God will have the last word. One cannot provoke Him, without experiencing a greater provocation by Him.
Lord, thank You for having the last word, and for shaming those who would try to shame You. You are so awesome!!! Help us This Day to hear every word You speak to us, and to walk in obedience. Amen.
