Rabbi Roodyn

יא) אֲשֶׁר נִשְׁבַּעְתִּי בְאַפִּי אִם יְבֹאוּן אֶל מְנוּחָתִי:

So that I swore in my wrath: ‘They shall not enter into my rest’.

Rav Hirsch sums up the chapter as follows:

This survey in retrospect of the experiences of the people of Israel gathered in the wilderness of Egypt is of great significance to our journey through the wilderness of ages.

Like our first journey through the desert, so our wanderings through exile should also serve to test us for the great, future destiny that awaits us. Even as it was throughout our first trek into the wilderness, so now too every moment of our survival through the wanderings of galus is the most valid proof of G-d’s nearness wherever we may travel, and it certainly should impart to us complete faith in G-d’s providence.

Then as now, the duration of our wanderings and our fate during this journey depend solely on our obedience to Hashem, and through מרד ופשע disobedience and defection from Him, we forfeit all our future.

Not only would we not succeed in our misdirected efforts toward absorption into the other national entities of the world, but also the future portion which was destined for us specifically for us as Jews would be denied us.
