Deuteronomy 4:9 Meaning and Commentary

Deuteronomy 4:9

Only take heed to thyself
To walk according to this law, and not swerve from it:

and keep thy soul diligently;
from the transgressions and breaches of it:

lest thou forget the things which thine eyes have seen;
either the statutes and judgments set before them, and the circumstances of the delivery of them; or the punishment inflicted on the breakers of them; or the favours bestowed on those that observed them:

and lest they depart from thy heart all the days of thy life;
out of thy mind and memory, and have no place in thy affections, through a neglect and disuse of them:

but teach them thy sons, and thy sons' sons;
their children and grandchildren, that they may be trained up in them in their youth, and so not depart from them when grown up, and in years; see ( Deuteronomy 6:7 ) .

Deuteronomy 4:9 In-Context

7 For what manner of nation great, which has God so near to them as the Lord our God in all things in whatsoever we may call upon him?
8 And what manner of nation great, which has righteous ordinances and judgments according to all this law, which I set before you this day?
9 Take heed to thyself, and keep thy heart diligently: forget not any of the things, which thine eyes have seen, and let them not depart from thine heart all the days of thy life; and thou shalt teach thy sons and thy sons' sons,
10 the day in which ye stood before the Lord our God in Choreb in the day of the assembly; for the Lord said to me, Gather the people to me, and let them hear my words, that they may learn to fear me all the days which they live upon the earth, and they shall teach their sons.
11 And ye drew nigh and stood under the mountain; and the mountain burned with fire up to heaven: darkness, blackness, tempest.
