Isaiah 8:2

And I took unto me faithful witnesses - What was the precise object in calling in these witnesses is not known. Some have supposed that it was to bear testimony to the marriage of the prophet at that time. But it may have been for the purpose of a public record of the prophecy; a record so made, that the precise time when it was delivered could be attested without dispute. The prophecy was an important one; and it was important to know, in the most authentic and undisputed manner, that such a prophecy had been delivered. It is probable that the prophecy, attested by the names of those two men, was suspended in some public place in the temple, so that it might be seen by the people, and allay their fears; and in order to remove from the multitude every suspicion that it was a prophecy after the event. That this was a real, and not a symbolic transaction, is perfectly manifest, not only from the narrative itself, but from Isaiah 8:18. They are called ' faithful,' not off account of their private character, but because their public testimony would be credited by the people.

To record - To bear witness.

Uriah the priest - This is, doubtless, the same man that is mentioned in II Kings 16:10. He was a man of infamous character; the accomplice of Ahaz in corrupting the true religion; but still his testimony might be the more valuable to Ahaz, as he was associated with him in his plans.

And Zechariah ... - It is not certainly known who this was. Perhaps he was one of the Levites whose name is mentioned in II Chronicles 29:13.
