Deuteronomy 11:21

21 so that you'll live a long time, and your children with you, on the soil that God promised to give your ancestors for as long as there is a sky over the Earth.

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 to your children. Talk about them wherever you are, sitting at home or walking in the street; talk about them from the time you get up in the morning until you fall into bed at night.
20 Inscribe them on the doorposts and gates of your cities
21 so that you'll live a long time, and your children with you, on the soil that God promised to give your ancestors for as long as there is a sky over the Earth.
22 That's right. If you diligently keep all this commandment that I command you to obey - love God, your God, do what he tells you, stick close to him -
23 God on his part will drive out all these nations that stand in your way. Yes, he'll drive out nations much bigger and stronger than you.
