“An instructor of the foolish, a teacher of babes, which hast the form of knowledge and of the truth in the law.”
King James Version (KJV)
2:20 Having the form of knowledge and truth - That is, the most accurate knowledge of the truth.
Ro 2:20 Which hast the form of knowledge. In the law they had the form, the pattern, of knowledge and of the truth. The truth in its fullness came with Jesus Christ (Joh 1:17), but the law was the pattern, the typical form, of this truth.
