First associated with this text in Fredrik Engelke's Loftangeroch andeliga wisor (1873), TRYGGARE KAN INGEN VARA is probably a Swedish folk song, but versions of the tune were also sung in Germany in the early 1800s.

This charmingly simple tune needs light accompaniment, perhaps just recorders 1 and guitars. It is well suited to part singing and could be sung unaccompanied.
