“And art confident that thou thyself art a guide of the blind, a light of them which are in darkness,”
King James Version (KJV)
2:19 Blind, in darkness, ignorant, babes - These were the titles which the Jews generally gave the gentiles.
Ro 2:19 A guide of the blind. It was God's purpose that in choosing Israel the Israelites should become teachers of the truth; but their sin was that while they boasted of this privilege they failed to do their duty. See Mt 15:14. Such a boast as this was current among the Jews of Paul's time. He heaps phrase on phrase to exalt their claims, in order to show in what follows how far short their lives fell of their professions.
