 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 the LORD: and his father and his mother that begat him shall thrust him through when he prophesieth.
Prophesy — Falsely.
His father — His dearest friends.
Shall thrust him through — That is, shall wound, shall chastise him with stripes that may leave their marks behind.
 And it shall come to pass in that day, that the prophets shall be ashamed every one of his vision, when he hath prophesied; neither shall they wear a rough garment to deceive:

 Awake, O sword, against my shepherd, and against the man that is my fellow, saith the LORD of hosts: smite the shepherd, and the sheep shall be scattered: and I will turn mine hand upon the little ones.

My fellow — This speaks Christ; man with us, and God with his father, God-man in one person.
The shepherd — This great and good shepherd.
Turn mine hand — God will turn his hand in favour, and for protection will keep the new, and weak disciples.
 And it shall come to pass, that in all the land, saith the LORD, two parts therein shall be cut off and die; but the third shall be left therein.

The third — A remnant, the lesser part, shall escape or be preserved.
