John Trapp on Psalms 10:17

Verſ. 17. Lord thou haſt heard the deſire of the humble] The whole life of a good Chriſtian is an holy deſire, ſaith Auſtin. And the deſires of the Righteous ſhall be ſatisfied, Prov. 10.24. becauſe they are framed by the Holy Spirit, according to the will of God, Rom. 8.27. and they have the mind of Chriſt, 1. Cor. 2.16. who knoweth the mind of the Spirit, Rom. 8.27. though their deſires be not uttered, v. 26.

Thou wilt prepare their heart] In removendis ab illo mundi negotiis, ſaith R. David, and by putting them into a praying frame, and ſo fitting them for mercy. Where God giveth a praying heart, 'tis ſure that hee will ſhew a pittying heart. If hee prepare the heart, hee will alſo bend his ear; like as when wee bid our Children ask us for this or that, wee mean to give it them; and as when wee open a purſe as wide as wee can pull it, 'tis a ſign wee intend to fill it top-full.

Thou wilt cauſe thine ear to hear] even whilſt they are preparing, and before they can ſpeak many times, Iſa. 65.24. or whileſt they are praying, as Dan. 9.20. Act. 4.31. or not long after; they ſhall be ſure to have out their prayers, either in mony, or in monies-worth, as they ſay.
