Thou art a port protected from storms which round us rise

Different denominations do things differently, and sometimes no one can remember why.

For example, this verse is not in every version of the hymn "O Day of Rest and Gladness", and I am not sure why.

"Thou art a port protected
From storms which round us rise;
A garden intersected
With streams of Paradise;
Thou art a cooling fountain
In life's dry, dreary sand;
From thee, like Pisgah's mountain,
We view our promised land. "

"O Day of Rest and Gladness" by Author: Christopher Wordsworth (1862) Trinity Hymnal #392 (1990) verse 3.
