Paul continues his imaginary argument with a Jewish person.

## If you call yourself a Jew ##

This begins a new section of the letter. Here the word "if" does not mean Paul doubts or is unsure. He is emphasizing that these statement are true. Alternate translation: "Now you think of yourself as member of the Jewish people"

## rest upon the Law, rejoice proudly in God ##

"and you rely on the Law of Moses and rejoice proudly because of God."

## know his will ##

This could be translated as a new sentence: "And you know God's will"

## having been instructed by the Law ##

This could be translated with an active verb: "because you understand what the Law of Moses teaches."

## if you are confident…and of the truth ##

If your language has a way to mark that 2:19-20 interrupts Paul's main argument of [Romans 2:17](./17.md), and [Romans 2:21](./21.md), use it here. You might have to place 2:19-20 before 2:17.

## if you are confident ##

"You are sure"

## that you yourself are a guide of the blind, a light to those who are in darkness ##

Both of these phrases mean basically the same thing. Paul compares a Jewish person teaching someone about the Law to helping a person that cannot see. Alternate translation: "that you yourself are like a guide to someone who is blind, and you are like a light to someone lost in the dark." (See: [[rc://en/ta/man/translate/figs-doublet]], [[rc://en/ta/man/translate/figs-metaphor]])

## a corrector of the foolish ##

This could be translated as a new sentence: "You correct those who do wrong."

## a teacher of babies ##

Here Paul compares those who do not know anything about the Law to babies. Alternate translation: "and you teach those who do not know the Law."

## and that you have in the Law the form of knowledge and of the truth ##

"because you are sure you understand the truth written in the Law"
