John Trapp on Proverbs 22:11

Verſ. 11. Hee that loveth pureneſs of heart] That is vexed at his inward pollutions, and affecteth (what hee can never fully effect) to be pure as God is pure, 1 Joh. 3.3. Hee that hath gotten that pure lip, Zeph. 3.9. called here the grace of his lips, Prov. 31.26. and elſewhere the Law of grace; Hee that can skill of thoſe good words that do ingratiate with God and man, Gen. 49.21. compared with Deut. 33.23. Hee is fit to make a Courtier, a Favourite; ſuch as was Joſeph, Mordecai, Daniel, who though hee uſed not alwayes verbis byſſinis, ſoft and ſilken words, but delivered heavy meſſages from God to Nebuchadnezzar and Belſhazzar, yet God ſo wrought their hearts (though Tyrants) that they greatly honoured him, and highly preferred him. And when, out of his love to pureneſs of heart, hee choſe rather affliction than ſin, to bee caſt to the Lions, than to bear a Lion in his own boſome by offending his conſcience: God made the Kings heart yearn towards him, &c. So that this plain-dealing Daniel proſpered in the reign of Darius, and in the reign of Cyrus the Perſian, Dan. 6.28.
