"Teach them diligently unto thy children"

In the Book of Deuteronomy, when the Israelites are about to enter into the promised land, they are admonished over and over to keep the judgments, statutes and commandments of the Lord. They are informed about the blessings that await if they do and warned about the curses that inevitably follow if they don't. This passage is particularly well-known 

4 Hear, O Israel: The Lord our God is one Lord:

5 And thou shalt love the Lord thy God with all thine heart, and with all thy soul, and with all thy might.

6 And these words, which I command thee this day, shall be in thine heart:

7 And thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thine house, and when thou walkest by the way, and when thou liest down, and when thou risest up.

8 And thou shalt bind them for a sign upon thine hand, and they shall be as frontlets between thine eyes.

9 And thou shalt write them upon the posts of thy house, and on thy gates. (Deuteronomy 6)

The Savior quotes verse 5 when he answers the famous question about the greatest commandment. But I wanted to focus on verse 7 about teaching the children. The NRSV Cultural Backgrounds Study Bible comments on this verse: 

The inculcation of moral principles and wisdom in youth was practiced widely in the ancient Near East. In Egypt, teaching and instruction were used from at least 2500 BC up until the time of the Ptolemies (c. 300 BC). Rules of conduct and learning were prepared for sons. From moral issues to royal protocol, children were trained in the home or in the king’s palace. Order, truth and justice were important. In Mesopotamia, Sumerian literature includes the advice of a father to his son. Several famous works of a didactic nature come from Mesopotamia. Repetition by mouth, copying texts and strict discipline (the rod!) were the main pedagogical means of “impressing” a desired curriculum on a student or child. This was done both in the home and in any place of learning available. Covenantal conditions and stipulations were passed on so that following generations would know and pursue them diligently

This is not the first time I read about ancient Israelite customs and see how well the Book of Mormon fits into that cultural framework. Especially the bolded parts are easily recognized in several Book of Mormon passages. Here are some examples:

Lehi's teachings to his sons

This is perhaps the best example of Near Eastern fatherly inculcation in the Book of Mormon. There are too many examples to go through in detail, but despite mixed outcomes, Lehi is quite clear about his objectives. 

28 And now, my sons, I would that ye should look to the great Mediator, and hearken unto his great commandments; and be faithful unto his words, and choose eternal life, according to the will of his Holy Spirit;

29 And not choose eternal death, according to the will of the flesh and the evil which is therein, which giveth the spirit of the devil power to captivate, to bring you down to hell, that he may reign over you in his own kingdom.

30 I have spoken these few words unto you all, my sons, in the last days of my probation; and I have chosen the good part, according to the words of the prophet. And I have none other object save it be the everlasting welfare of your souls. Amen. (Nephi 1-4)

The way of life and the way of death is the essence of Deuteronomy and this is what Lehi lays out in this chapter. "I have none other object save it be the everlasting welfare of your souls" is really strong language. All of 2 Nephi 1-3 and some of chapter 4 is Lehi's "advice of a father to his son" with "covenantal conditions and stipulations...passed on so that the following generations would know and pursue them diligently"

5 But, said he, notwithstanding our afflictions, we have obtained a land of promise, a land which is choice above all other lands; a land which the Lord God hath covenanted with me should be a land for the inheritance of my seed. Yea, the Lord hath covenanted this land unto me, and to my children forever, and also all those who should be led out of other countries by the hand of the Lord. (2 Nephi 1)

3 Wherefore, after my father had made an end of speaking concerning the prophecies of Joseph, he called the children of Laman, his sons, and his daughters, and said unto them: Behold, my sons, and my daughters, who are the sons and the daughters of my firstborn, I would that ye should give ear unto my words.

4 For the Lord God hath said that: Inasmuch as ye shall keep my commandments ye shall prosper in the land; and inasmuch as ye will not keep my commandments ye shall be cut off from my presence.

5 But behold, my sons and my daughters, I cannot go down to my grave save I should leave a blessing upon you; for behold, I know that if ye are brought up in the way ye should go ye will not depart from it.

6 Wherefore, if ye are cursed, behold, I leave my blessing upon you, that the cursing may be taken from you and be answered upon the heads of your parents.

7 Wherefore, because of my blessing the Lord God will not suffer that ye shall perish; wherefore, he will be merciful unto you and unto your seed forever. (2 Nephi 4) 

We could go on but this sample is sufficient to illustrate the point. 

King Benjamin's teachings to his sons

This account is much briefer but sufficient to see the ancient Near Eastern cultural heritage

2 And it came to pass that he had three sons; and he called their names Mosiah, and Helorum, and Helaman. And he caused that they should be taught in all the language of his fathers, that thereby they might become men of understanding; and that they might know concerning the prophecies which had been spoken by the mouths of their fathers, which were delivered them by the hand of the Lord.

3 And he also taught them concerning the records which were engraven on the plates of brass, saying: My sons, I would that ye should remember that were it not for these plates, which contain these records and these commandments, we must have suffered in ignorance, even at this present time, not knowing the mysteries of God.

4 For it were not possible that our father, Lehi, could have remembered all these things, to have taught them to his children, except it were for the help of these plates; for he having been taught in the language of the Egyptians therefore he could read these engravings, and teach them to his children, that thereby they could teach them to their children, and so fulfilling the commandments of God, even down to this present time.

7 And now, my sons, I would that ye should remember to search them diligently, that ye may profit thereby; and I would that ye should keep the commandments of God, that ye may prosper in the land according to the promises which the Lord made unto our fathers.

8 And many more things did king Benjamin teach his sons, which are not written in this book.

Apparently, this account is very abbreviated, and King Benjamin taught his sons "many more things". In verse 4, King Benjamin seems to refer to Deuteronomy 6:7, probably among other things, where the commandment to teach the word of God to your children is given.

Alma-II to his sons

I am sure that all the righteous record keepers in the Book of Mormon had similar teaching sessions to their sons, even though not all have been recorded. But Mormon decided to include Alma's word to his sons and take them directly from his own record. Here we see the same pattern, especially with Helaman who is the oldest and the next record keeper.

13 O remember, remember, my son Helaman, how strict are the commandments of God. And he said: If ye will keep my commandments ye shall prosper in the land—but if ye keep not his commandments ye shall be cut off from his presence...

17 For he will fulfil all his promises which he shall make unto you, for he has fulfilled his promises which he has made unto our fathers...

20 Therefore I command you, my son Helaman, that ye be diligent in fulfilling all my words, and that ye be diligent in keeping the commandments of God as they are written....

35 O, remember, my son, and learn wisdom in thy youth; yea, learn in thy youth to keep the commandments of God. (Alma 37)

The bold parts are directly linked to the quoted description of the ancient Israelite practice of fathers teaching their sons.
