John Trapp on Zechariah 9:17

Verſe 17. For how great is his goodneſſe] He ſhuts up all with this ſweet Epiphonema, or exclamation, admiring the ſingular goodneſſe of God to his people in all the former particulars: and yet promiſing them Abundance of outward neceſſaries, even to an honeſt affluence: they ſhould have ſtore of corn and wine; ſo much as ſhould make them ſucculent and vigorous, full of ſappe and good humours. Provided, that firſt they content not themſelves with the naturall uſe of the creature, but taſt how good the Lord is. And next, that they put this promiſe into ſuit by their prayers, as chap. 10.1.
