KJV
"How can you say, "We are wise, for we have the law of the LORD," when actually the lying pen of the scribes has handled it falsely?"
NIV
How can you say, We are wise, and we have the written law of the Lord [and are learned in its language and teachings]? Behold, the truth is, the lying pen of the scribes has made of the law a falsehood (a mere code of ceremonial observances). [Mark 7:13.]AMP
How do ye say, We are wise, and the law of the LORD is with us? Lo, certainly in vain made he it; the pen of the scribes is in vain.
