John Trapp on Isaiah 40:7-8

Ver. 7. Becauſe the ſpirit of the Lord bloweth upon it] Or, when the breath of the Lord bloweth upon it. God can eaſily blow men to deſtruction, diſſipate them as ſo many vile duſtheaps, Job 4.9. and 34.14, 15. Pſal. 104.29. Dan. 2.34, 35. Zach. 4.6.

Surely the people is graſſe] Have we not heard? have we not ſeen from the beginning? doth not every dayes experience ſeal to it, that all fleſh is graſſe? yea hath not God oft heard our atteſtations? We ſhake our heads, we confeſſe it is true, &c. and yet we lay it not rightly to heart, though ſo deeply aſſevered and aſſured us.

Ver, 8. But the Word of our God ſhall ſtand for ever] q. d. Though the Elect alſo as well as others are graſs, fraile and fading creatures, yet the grace of God wrought in their hearts by the Goſpel, is ſtable and laſting, See 1 Pet. 1.23. with the Note. And ſo neceſſary is this whole doctrine here delivered, that the Miniſters of the Goſpel are commanded here not to write it only, but to ſpeak it: nor that only, but to cry it alſo, with all poſſible both affection and power of inforcement.
