John Trapp on Psalms 96:2

Verſ. 2. Sing unto the Lord, &c.] David was at this time full of affection, and exultation of Sprit (inſomuch as Michal mocked him for it, 1 Chron. 15.29.) and thence this heap of holy expreſſions to the ſame purpoſe. Out of the abundance of the heart, the mouth ſpeaketh.

Shew forth his ſalvation] Evangelize, Preach the Goſpel of ſalvation by Chriſt; ſee Pſal. 40.10. 2 Sam. 18.18. Iſa. 61.1. where the ſame word is uſed.

Form day to day] Other news delights us only at firſt hearing; but the good news of our redemption is ſweet from day to day, ac ſi in eodem die redemptio fuiſſet operata, ſaith Kimchi here, as if it were done but to day. Tam recens mihi nunc Chriſtus est, ſaith Luther, ac ſi hac horâ fudiſſet ſanguinem, Chriſt is now as freſh unto mee as if he had ſhed his blood but this very hour.
