John Trapp on Proverbs 4:13

Verſ. 13. Take faſt hold of inſtruction] Nam magnum certamen ſuſtines adverſus haereticos & Epicureos, ſaith a Jew-Doctor upon this Text, Hereticks and Epicures will ſeek to wring it from thee, by wrench and wile. Therefore hold faſt the faithful word, as thou haſt been taught, Tit. 1.9. Hold it as with tooth and nail, againſt thoſe gain-fayers, that would ſnatch it from thee. For th[illegible: 3 letters] are many unruly and vain talkers, &c. and ſo there are many looſe and lewd walkers too, that would bereave thee of the benefit of what thou haſt learned: but hold faſt that which is good: Let it not go, Ne langueſcas, furceaſe not, ſlake not, give not over ſtriving againſt ſin and ſinners.
