Isaiah 30 - 35

Amidst the prophecies and warnings of Isaiah to his people and those of the latter days, he teaches some great truths and responsibilities of the righteous. First he asks -

"Whom shall he teach knowledge? and whom shall he make to understand doctrine? them that are weaned from the milk, and drawn from the breasts.
10 For precept must be upon precept, precept upon precept; line upon line, line upon line; here a little, and there a little..." (Old Testament Isaiah 28:9 - 10)

This is done as -

"...the word of the LORD was unto them precept upon precept, precept upon precept; line upon line, line upon line; here a little, and there a little..." (Old Testament Isaiah 28:13)

Isaiah then takes this concept and talks of the people in our day -

"Wherefore the Lord said, Forasmuch as this people draw near me with their mouth, and with their lips do honour me, but have removed their heart far from me, and their fear toward me is taught by the precept of men:
14 Therefore, behold, I will proceed to do a marvellous work among this people, even a marvellous work and a wonder: for the wisdom of their wise men shall perish, and the understanding of their prudent men shall be hid..." (Old Testament Isaiah 29:13 - 14)

Part of that marvelous work is the coming forth of the Book of Mormon as a second testament of Jesus Christ -

"And in that day shall the deaf hear the words of the book, and the eyes of the blind shall see out of obscurity, and out of darkness.
19 The meek also shall increase their joy in the LORD, and the poor among men shall rejoice in the Holy One of Israel." (Old Testament Isaiah 29:18 - 19)

Isaiah's prophecies fulfilled as -

"...as the words of a book that is sealed, which men deliver to one that is learned, saying, Read this, I pray thee: and he saith, I cannot; for it is sealed:
12 And the book is delivered to him that is not learned, saying, Read this, I pray thee: and he saith, I am not learned." (Old Testament Isaiah 29:11 - 12)

Joseph Smith records that in 1828 -

"Sometime in this month of February, the aforementioned Mr. Martin Harris came to our place, got the characters which I had drawn off the plates, and started with them to the city of New York. For what took place relative to him and the characters, I refer to his own account of the circumstances, as he related them to me after his return, which was as follows:
64 "I went to the city of New York, and presented the characters which had been translated, with the translation thereof, to Professor Charles Anthon, a gentleman celebrated for his literary attainments. Professor Anthon stated that the translation was correct, more so than any he had before seen translated from the Egyptian. I then showed him those which were not yet translated, and he said that they were Egyptian, Chaldaic, Assyriac, and Arabic; and he said they were true characters. He gave me a certificate, certifying to the people of Palmyra that they were true characters, and that the translation of such of them as had been translated was also correct. I took the certificate and put it into my pocket, and was just leaving the house, when Mr. Anthon called me back, and asked me how the young man found out that there were gold plates in the place where he found them. I answered that an angel of God had revealed it unto him.
65 "He then said to me, 'Let me see that certificate.' I accordingly took it out of my pocket and gave it to him, when he took it and tore it to pieces, saying that there was no such thing now as ministering of angels, and that if I would bring the plates to him he would translate them. I informed him that part of the plates were sealed, and that I was forbidden to bring them. He replied, 'I cannot read a sealed book.' I left him and went to Dr. Mitchell, who sanctioned what Professor Anthon had said respecting both the characters and the translation."
(Pearl of Great Price JS-History 1:63 - 65)

I began this blog, I mentioned Isaiah gave instructions of the responsibilities of the righteous being -

"Strengthen ye the weak hands, and confirm the feeble knees.
4 Say to them that are of a fearful heart, Be strong, fear not..." (Old Testament Isaiah 35:3 - 4)

As was also reiterated in modern day -

"Wherefore, be faithful; stand in the office which I have appointed unto you; succor the weak, lift up the hands which hang down, and strengthen the feeble knees." (Doctrine and Covenants Section 81:5)
