John Gill Commentary Deuteronomy 11

Therefore you shall love the Lord your God
Because he is so great and glorious in himself, and because he had done such great and good things for them, the Israelites, particularly in the multiplication of them, the last thing mentioned:

and keep his charge ;
whatsoever the Lord had charged them to observe, even what follow:

and his statutes and his judgments, and his commandments, always ;
all his laws, ceremonial, judicial, and moral; and that constantly and continually, all the days of their lives.

And know you this day
Take notice of, and diligently attend unto, what is now about to be delivered:

for I speak not unto your children which have not known, and which have
not seen, the chastisement of the Lord your God ;
who have no knowledge and experience of the chastisement of the Lord on themselves, or on their foes or friends; and with whom the argument drawn from it could not come with that force, and make that impression, as it might be thought it would, being used with them who had perfect knowledge of it.

The Targums of Onkelos and Jonathan render it doctrine, which, being children, they were not instructed so perfectly in as they were who were adult persons, to whom Moses directs his discourse:

his greatness, his mighty hand, and stretched out arm :
the exceeding greatness of his power, displayed in the following instances.

And his miracles, and his acts, which he did in the midst of
Egypt
The miraculous works done there, the ten plagues inflicted on the Egyptians for refusing to let Israelgo:

unto Pharaoh king, of Egypt, and unto all his land ;
for those plagues not only affected him and his court, and his metropolis, but all parts of the land, theinhabitants of it everywhere.

And what he did to the army of Egypt, to their horses, and
to their chariots
At the Red sea, when they pursued Israel in order to bring them back or destroy them, after they had let them go, which army was very numerous; see (Exodus 14:7Exodus 14:9)

how he made the water of the Red sea to overflow them ;
"or to flow over their faces" ^F2 ,

as they pursued after you ;
so that they could not see their way, nor steer their course after them; and not only so, but were covered with the waters of the sea, drowned in them, and sunk to the bottom of them: and how the Lord has destroyed them to this day; either continued to destroy them yet more and more by one means or another; or else the destruction made by the several plagues upon them, and particularly that of their army at the Red sea, which was the strength and glory of the nation, was so general and extensive, that they never recovered it to that day; and so were in no capacity of coming out against them, and attacking them, and doing them any hurt, all the forty years they had been in the wilderness; of which no doubt they had knowledge, and of their condition and circumstances there.

And what he did unto you in the wilderness, until you came
unto this place .
] Meaning not so much the good things he did for them in divers places, as the chastisements and corrections he had exercised them with for their murmurings, rebellions, idolatry, and uncleanness, as at Taberah, Kibrothhattaavah, on the coast of Edom, and plains of Moab; by fire, by sword, by plagues, and fiery serpents; the instances both before and after being of this sort.
