John Trapp on Psalms 21:3

Verſ. 3. For thou preventeſt him with the bleſſings of goodneſs] Not ſtaying till he asked them of thee. He had but a thought of building thee an houſe, and thou ſenteſt Nathan to tell him, that thou wouldſt build him an everlaſting houſe, and ſtabliſh his Throne to all perpetuity, 2 Sam. 7.16. So Iſa. 65.1. Before they call, I will anſwer, &c.

Thou ſetteſt a Crown of pure gold upon his head] Hebrai dicunt per hoc intelligi favorem Dei, the Jew-Doctors by this Crown underſtand the favour of God; confer Pſal. 103.4. God had ſet a Crown of loving kindneſs, and tender mercies upon his head, by pardoning all his iniquities, as it is there; and he bleſſeth God for this as a farre better Crown, than that which he took from off the head of the King of Ammon, and ſet upon his own, 2 Sam. 12.30.
