Deuteronomy 11:21 Meaning and Commentary

Deuteronomy 11:21

That your days may be multiplied
Long life being a very desirable blessing, and which is promised to those that obey and keep the law; see ( Deuteronomy 30:19 Deuteronomy 30:20 ) ( Psalms 91:16 )

and the days of your children;
which are dear to parents, and the continuance of whose lives, next to their own, is most desirable, yea, as desirable as their own; and especially it is desirable that they might have a posterity descending from them, to enjoy for ever their estates and possessions; as it was to the people of Israel, that they might have a seed always to dwell

in the land which the Lord sware unto your fathers to give them;
the land of Canaan, so often spoken of as the promise, oath, and gift of God:

as the days of heaven upon the earth;
that is, as long as the heavens and the earth shall be, and the one shall be over the other, as they will be to the end of time.

Deuteronomy 11:21 In-Context

19 And ye shall teach them to your children, speaking of them when thou sittest in thine house and when thou walkest by the way, when thou liest down and when thou risest up.

20 And thou shalt write them upon the doorposts of thine house and upon thy gates,

21 that your days may be multiplied, and the days of your children, in the land which the LORD swore unto your fathers to give them, as the days of heaven upon the earth.

22 For if ye shall diligently keep all these commandments which I command you to do them -- to love the LORD your God, to walk in all His ways, and to cleave unto Him--

23 then will the LORD drive out all these nations from before you, and ye shall possess greater nations and mightier than yourselves.
