Matthew Poole’s Commentary

Ver. 16. These are, by the consent of all, God’s words to the prophet.  By the testimony and the law or doctrine (for so this word is frequently taken) he understands one and the same thing, as he doth also to wit, the word of God, and especially that which is the main scope and substance thereof, the doctrine of the Messias, which, though now professed by all the Israelites, shall be disowned by the generality of them, when the Messiah shall come.

Bind up and seal are to be understood prophetically, Declare and prophesy that it shall be bound up and sealed; as Isaiah is said to make fat, and to blind, &c. Isa 6:10, and Jeremiah to root out and pull down, &c., Jer 1:10, when they foretell these events. Moreover, bind up and

seal design the same thing, and that is, either,

1. Security and certainty, as things are bound up or sealed that they may not be lost. So he signifies, that although this doctrine would be lost among the body of the Israelites, yet it should be preserved among his disciples. Or,

2. Secrecy, as many things are bound up or sealed that they may be hid from the eyes of others. And so he informeth them that this doctrine now was and should be hid in a great measure among all God’s people, even till the accomplishment of it; and that even when it was accomplished, it should still continue to be as a secret and mystery, known indeed to his true disciples, but hid from the body of the nation, who would not see it, and therefore should be blinded by God’s just judgment, that they should not see it, as was prophesied, Isa 6:9,10. Or,

3. Both security and secrecy, signifying that it should certainly be fulfilled, yet withal kept secret from the unbelieving Jews. For why may not these two be joined in the exposition of this text, as they were in the event? By God’s disciples he means those who were taught of God, as it is expressed, Isa 54:13, where this very word is used; or, every one that hath heard and learned of the Father, and therefore cometh unto Christ, as it is explained, Joh 6:45.
