John Trapp on Isaiah 63:15

Ver. 15. Look down from heaven] Affectus dolentium atque ardenter petentium ſcite exprimuntur: a pathetical and pithy prayer.

And behold from the habitation of thy holineſs, &c.] They pray otherwiſe now, then when the Temple ſtood, Pſal. 121.1. now they look higher: and Oh that they would do ſo! The modern Jews pray thus daily; but becauſe not from a right principle, they are not heard.

Where is thy zeal?] Thine ancient fervour, and forwardneſs in vindicating thy people, and being avenged of their enemies.

The ſounding (rumbling or yerning) of thy bowels, &c.] Sometimes God ſeemeth to looſe his mercy, and then we muſt find it for him, as here: ſometimes to ſleep or delay, and then we muſt waken quicken him, Pſal. 40.17. Iſa. 62.7.

Are they reſtrained?] Chryſoſtom exhorteth people, whether God grant or not, to pray ſtill; for when God denies, it is as good as if he grants: And if we pray for any temporal mercy, the very ability to pray, Hom. 30. in Gen ſ. is better then the thing we pray for; for Whoſoever calleth upon the name of the Lord, ſhall be ſaved.
