פירוש על שמואל ב 7:9

Like the name of great people. That is what is said [about Dovid] the shield of Dovid.⁷Pesachim 117b. The “great people” referred to here are Avrohom, Yitzhok and Yakov. Just as they are mentioned in the first blessing of the Amidah, so too Dovid’s name is used in the ending of one of the Haftorah’s concluding blessings. (Rashi, ibid).

I will destroy all your enemies. And that is why [the thought] came to your heart to build the House as it is written in the Torah.⁸Devarim 12:10. See Rashi on verse 1.
