John Trapp on Ezra 7:10

Verſe 10. For Ezra had prepared his heart] Which, without due preparation, would not have beene drawne to any good. See 1 Sam. 7.3. Job 11.13. Amos 4.12. An inſtrument muſt be tuned, ere it can be plaid upon: ſowre wines need good ſweetening.

To ſeek the Law of the Lord] To dive into the very boſome and bottome of it. Qui nucleum vult, nucem frangat. The Rabbines have a ſaying, that there is a mountaine of ſenſe hanging upon every tittle of Gods Law.

And to do it] His knowledge and practiſe ran parallel, and mutually transfuſed warmth into one another. He was not of thoſe Oratours blamed by Diogenes, for that they ſtudied benè dicere, non benè facere, to ſpeak commendably, but not to live accordingly. He knew well that his forefathers (the High Prieſts) had Pomegranates for ſavour, as well as bells for ſound.

And to teach in Iſrael] He knew the truth of that Hebrew Proverb, Lilmod Lelammed. Men muſt therefore learne, that they may teach others; and not bury their talents, leſt the canker of their great skill prove a ſwift witneſſe one day againſt them.
