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 them carefully to your children, talking about them when you sit at home, when you are traveling on the road, when you lie down and when you get up;

20 and write them on the door-frames of your house and on your gates -

21 so that you and your children will live long on the land ADONAI swore to your ancestors that he would give them for as long as there is sky above the earth. (vii & Maftir)

22 "For if you will take care to obey all these mitzvot I am giving you, to do them, to love ADONAI your God, to follow all his ways and to cling to him,

23 then ADONAI will expel all these nations ahead of you; and you will dispossess nations bigger and stronger than you are.
