What is written in the law?.... Christ, with great propriety, sends him to the law, to see and observe what was written there, what are the terms and conditions of life, as fixed there; partly, because this man, by his office and character, was an interpreter of the law; and partly, because his question was, what shall I do?
how readest thou? in the law, every day; referring to the "Keriat Shema", the reading of the Shema, i.e. those words in De 6:4, &c, "Hear, O Israel, &c." morning and evening as appears by his answer Vid.
