John Trapp on Isaiah 28:10

Ver. 10. For precept muſt be upon precept] Children are of weak underſtanding, and of ſhort memories; and Hebraei dicunt hiſce verbis infantilitatem ſignificari, they muſt alſo have ſhort words and ſentences preſcribed unto them (ſuch as are kau and flau) and inculcated upon them, that ſomething at leaſt may ſtick: ſo muſt moſt of our Hearers, or little good will be done, Deut. 6.7. thou ſhalt teach them diligently unto thy Children, Heb. thou ſhalt whet or repeat them by often going over the ſame thing, as the knife goeth over the whetſtone till it be ſharp. But very many of our common hearers are not only unteachable, but untameable, deriding ſound doctrine, and making a mocking ſtock of their godlieſt Miniſters. And ſo ſome very good Expoſitors, haec [non-Latin text not transcribed] & [non-Latin text not transcribed] à Prophetadici tradunt, make theſe words here recited to be the ſcoffs and taunts of thoſe profane mockers, ver. 14. & 22. which they put upon the Prophet; q. d. We have nothing but rule upon rule, precept upon precept, &c. Zaulazau, kau lakau, the very ſound of the words carrieth a jear; like as ſcornful people by the tone of their voice and riming words, ſcorn at ſuch as they deſpiſe: Thus this good Prophet became the drunkards ſong. Any man may be witty in a biting way: and thoſe that have the dulleſt brains, have commonly the ſharpeſt teeth to that purpoſe. Rightly ſaid the Comedian, Homine imperito nunquam quicquam injuſtius; Terent.Qui, niſi quod ipſe fecit, nihil rectum putat.
