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 Teach your children that they meditate on them, when thou sittest in thy house, and when thou walkest on the way, and when thou liest down and risest up.

20 Thou shalt write them upon the posts and the doors of thy house:

21 That thy days may be multiplied, and the days of thy children in the land which the Lord swore to thy fathers, that he would give them as long as the heaven hangeth over the earth.

22 For if you keep the commandments which I command you, and do them, to love the Lord your God, and walk in all his ways, cleaving unto him,

23 The Lord will destroy all these nations before your face, and you shall possess them, which are greater and stronger than you.
