John Trapp on Job 35:13

Verſe 13. Surely God will not hear vanity] Prayer without Faith, is but an empty ring, a tinkling cymbal. Neque enim omnes qui citharam habent, ſunt citharoedi; Every ſound is not Muſick, neither is every complaint and out-cry of men in extremity, an effectual Prayer. Thoſe in Hoſea, when pined almoſt, howled as Dogs, growled as Swine, bellowed as Bulls, ſcreeched horribly as the Ravens of Arabia, Hoſ. 7.14 but becauſe they cryed not to God with their hearts, he heard them not. It is not the labour of the lips, or the loudneſſe of the voice, but the travel of the heart, and truth in the inward parts that he regardeth: Pſal. 51.6. Wilt thou not know, O vain (or empty) man, that Faith without Works is dead? ſaith St. James chap. 2.20. ſo that prayer without faith is to no purpoſe? Men may cry aloud in diſtreſſe, and make their voices to be heard on high; they may chatter out a charm when Gods chaſtening is upon them, yea, be with child, as it were, of a prayer, yet bring forth nothing better than wind, work no deliverance at all in the earth, Iſai. 26.16, 17, 18. God may turn them off, and juſtly, with Depart ye workers of iniquity; get you to the gods whom ye have choſen, let them deliver you in the time of your tribulation: for I will deliver you no more, Judg. 10. verſ. 13, 14.

Neither will the Almighty regard it] Heb Look intently into it. It is other, and better fruit of affliction that he looketh for. Whereof miſſing, he looketh another way, as it were, and taketh no notice of their prayers, or preſſures. Hence they deny, or at leaſt doubt of the divine providence: and are ready to let fly at God, as the Chineſes whip their gods, if they help them not at a call.
