Psalms 48:2

This is the Psalm of the Day for Monday. The Talmud (Rosh Hashana 31a) explains the reason each day was assigned a given Psalm. This verse was selected for Monday – the second day - because it says that G-d is great. On the second day of Creation, G-d separated the Heavens and the Earth, and ruled over them. This is a demonstration of His greatness.
