John Trapp on Proverbs 14:13

Verſ. 13. Even in laughter the heart is ſorrowful] Nulla eſt ſincera voluptas. Labor eſt etiam ipſa voluptas. Of carnal pleaſures a man may break his neck, before his faſt. All this avails mee nothing, ſaid Haman. Omnia fui, & nihil profuit, ſaid that Emperour. Vanity of vanity, all is vanity, ſaid Solomon, and not vanity onely, but vexation of ſpirit. Nothing in themſelves, and yet full of power and activity to inflict vengeance and vexation upon the ſpirit of a man; ſo that even in laughter, the heart is ſorrowful. Some kinde of frothy and flaſhy mirth wicked men may have; ſuch as may wet the mouth, but not warm the heart, ſmooth the brow, but not fill the breaſt: It is but a cold armful, as Lycophron ſaith of an evil wife; as they repent in the face, Mat. 6.16. ſo they rejoyce in the face, [non-Latin text not transcribed]. Lyc. not in the heart, 2 Cor. 5.12. Rident & ringuntur; there is a ſnare or a cord in the ſin of the wicked, that is, to ſtrangle their joy with, but the righteous ſing and are merry, Prov. 29.6. Others may revel, they onely muſt rejoyce, Hoſ. 9.1.

And the end of that mirth is heavineſs] They dance to the Timbrel and Harp, but ſuddenly they turn into Hell, Job 21.12, 13. and ſo their merry dance ends in a miſerable downfal.Luk. 6. Woe bee to you that laugh now. Thoſe merry Greeks (that are ſo afraid of ſadneſs, that they baniſh all ſeriouſneſs) ſhall one day wring for it. Adoniah's gueſts had ſoon enough of their good cheer and jollity: So had Belſhazzar and his combibones optimi. Thou mad fool, what doſt thou? Eccleſ. 2. ſaith Salomon to the mirth-monger, that holds it the onely happineſs to laugh and bee fat. Knoweſt thou not yet there will bee bitterneſs in the end? Principium dulce eſt, ſed finis amoris amarus, The candle of the wicked ſhall be put out in a vexing-ſnuff. Their mirth (as Comets) blazeth much, but ends in a peſtilent vapour. As lightning it ſoon vaniſheth, leaveth a greater darkneſſe behinde it, and is attended with the renting and roaring thunder of Gods wrath.
