If Gideon's fleece, which drenched with dew he found,
White moisture none refreshed the herbs around,
Might fitly represent the Church, endowed
With heavenly gifts to heathens not allowed;
In pledge, perhaps, of favours from on high,
Thy locks were wet when others' locks were dry.
Heaven grant us half the omen,--may we see
Not drought on others, but much dew on thee!

William Cowper
