We reviewed perek 91 of Tehilim focusing on the last 2 psukim,
We reviewed the commentaries that discuss the protection of Hashem is dependent on our connection to Hashem, as well as the Malbim who says that the pasuk is teaching us that Hashem is there with us in our distress, and that our salvation is his salvation.
