{7} Did not Moses give you the law, and yet none of you keepeth the law? Why go ye about to kill me?

(7) None boast more confidently that they themselves are the defenders of the law of God than they that break it most impudently.

People's New Testament

7:19 Did not Moses give you the law? Yet they were seeking to kill him in violation of the law which they professed to keep.

Wesley's Notes

7:19 But ye are unrighteous; for ye violate the very law which ye profess so much zeal for.

Jamieson-Fausset-Brown Bible Commentary

19, 20. Did not Moses, &c.-that is, In opposing Me ye pretend zeal for Moses, but to the spirit and end of that law which he gave ye are total strangers, and in "going about to kill Me" ye are its greatest enemies.

Matthew Henry's Concise Commentary

7:14-24 Every faithful minister may humbly adopt Christ's words. His doctrine is not his own finding out, but is from God's word, through the teaching of his Spirit. And amidst the disputes which disturb the world, if any man, of any nation, seeks to do the will of God, he shall know whether the doctrine is of God, or whether men speak of themselves. Only those who hate the truth shall be given up to errors which will be fatal. Surely it was as agreeable to the design of the sabbath to restore health to the afflicted, as to administer an outward rite. Jesus told them to decide on his conduct according to the spiritual import of the Divine law. We must not judge concerning any by their outward appearance, but by their worth, and by the gifts and graces of God's Spirit in them.
