Midrash sa Mga Awit 2:10: Ein Yaakov (Glick Edition) & Midrash Tehillim

Let us see: The passage (Ps. 19, 15.) May the words of my mouth he acceptable, can be explained in the past tense, and it may be explained in the future tense. Why then have the Rabbis decided to say it after the Eighteen Benedictions and not before? R. Juda, the son of R. Simon b. Pazi, said: "Because David did not say this verse until after he had said eighteen chapters, therefore did the Rabbis decree [to say it] after the Eighteen Benedictions." Is it after eighteen? Behold! it is after nineteen? Aye! the first two chapters, viz., Happy is the man, and Wherefore do heathens rage, are only one chapter, for R. Juda, the son of R. Simon b. Pazi, said: "One hundred and three chapters were uttered by David, and he did not say Hallelujah until he had contemplated the downfall of the wicked; as it is said (Ps. 104, 35.) Let the sinners be taken completely out of the earth, and let the wicked be no more; Bless the Lord, O my soul. Hallelujah! Instead of one hundred and three, we ought to say, one hundred and four? but we infer this, that Blessed is the man, and Why do the heathens rage, are but one psalm. (Fol. 10a) As R. Samuel b. Nachmeini in the name of R. Jonathan said: 'Every chapter that was beloved by David, he began and concluded it with the word, Happy; It began with Happy is the man (Ps. 1, 1), and ended with Happy are all they that put treir trust in Him (Ib. 2, 10).' [This proves that the first two chapters are one]."

“Be sincere [literally: kiss with purity]” (Psalms 2:12). [Once again, the Midrash reads the verse as “kiss the wheat”; or more specifically, “kiss the bread”]. Rav and Rav Acha said, “kiss the bread of the Torah,” as it is said, “Come and eat my bread” (Proverbs 9:5). [They should do so] before [God’s] attribute of justice stands up against them, and the way of the Torah will be lost [to them]; “your way [will] be doomed” (Psalms 2:10). You shouldn’t think that I require camps [of troops] with trumpets. Rather, I need just one spark, and I will ignite [a flame] and destroy the world that I created.
