Charles Spurgeon Commentary Zechariah 13:3

"And it shall come to pass that, when any shall yet prophesy, then his father and his mother that begat him shall say unto him, Thou shalt not live; for thou speakest lies in the name of Jehovah; and his father and his mother that begat him shall thrust him through when he prophesieth." — Zechariah 13:3 (ASV)

And it shall come to pass, that when any shall yet prophesy,–

When any false prophet will still pretend to prophesy,–

Then his father and his mother that begat him shall say unto him, Thou shalt not live; for thou speakest lies in the name of the LORD: and his father and his mother that begat him shall thrust him through when he prophesieth.

So intense will be the hatred of false prophets, that people will not spare even their own children. They will abhor them when they stand up against the Lord of hosts and against his truth.

It was a part of the law of God in the Book of Deuteronomy that any man who professed to be a prophet, and who sought to turn the people aside to the worship of idols, should be put to death. It is here declared that when God had cleansed the land, there would be no false prophets. And if any man pretended to be a prophet of the Lord when he was not sent by God, his own father and mother would be the first to execute judgment on him.
