John Trapp on Psalms 21:2

Verſ. 2. Thom haſt given him his hearts deſire] Good m[illegible: 1 letter]n are ſure to have out their prayers either in mony, or in monies worth, as they ſay; in that very thing they deſire, or a better. If God croſs them, it is in faithfulneſs to their Souls: when the wicked boaſteth of his hearts deſire, Pſal. 10.3. which yet he hath for a miſchief. Deus ſaepe dat iratus, quod neg at propitius. See the Note on Pſal. 20.4.

And hath not with-holden, &c. Selah] Ac ſi dicat, O magnam & admirabilem Dei benevolentiam erga Davidem! ſaith Vatablus. This Selah is added here, to ſet forth the very great and wonderful love of God to David, in hearing his Sutes after that ſort.
