John Trapp on Psalms 94:12

Verſ. 12. Bleſſed is the man whom thou chaſteneſt, &c.] And thereby effecteſt, that his vain thoughts lodge not within him, Jer. 4.14. but that the wicked forſake his wayes, and the unrighteous man his thoughts, and return to thee, &c. Iſa. 55.7. Feri Domine, feri, ſaid Luther, ſtrike whiles thou pleaſeſt, Lord; only to thy correction adde inſtruction, Ʋt quod noceat, doceat. See my Lovetokens.

And teachest him out of thy law] Laſhing him, but withall leſſoning him, ut reſipiſcat, & ſerviat tibi corde perfecto, ſaith Kimchi here, that he may repent and ſerve thee with an upright heart; for which purpoſe affliction ſanctified is of ſingular uſe. Crux voluntat is Dei ſchola, morum diſciplina, felicitatis meditatorium, gau dii Spiritus ſancti officina, breviter bonorum omnium theſaurus, ſaith Brentius on Job 33.16.
