Hymn and writer search - As once the sacrificial blood

[Russell L]

I'm trying to discover who the writer is, of a hymn the first verse of which is:

As once the sacrificial blood
On doors and lintel posts
Brought Israel scatheless through the flood
And scattered Egypt's hosts,

Any clues please??

[david z crookes]

The hymn was written by the late Enoch Powell.
