Mit '... what e'er the tide' (whatever the tide) würde es für mich Sinn machen:

'... was (auch) immer kommt [Flut oder Ebbe / (Hochs oder Tiefs)]' . . .

Könnte es nicht vielleicht "betide" heißen?

Es erinnert mich ein wenig an die Zeile "He'll give Thee strength whate'er betide thee" (Her wird dir Stärke verleihen, was auch immer dir widerfährt)

Just a suggestion...

second Nico: It's "betide" not "be tide"

Reminds me of a Billy Connolly sketch from his schooldays. His headmaster kept threatening: "Woe betide the boy who doesn't do his homework"... plays truant etc

Billy's comment: "...for years I thought 'woe betide the boy who doesn't turn up for class' was a boy called Wobie Tide. I thought, 'good ol' f****** Wobie!' " -

Hence, you could translate it like this:

"Sei nicht bestürzt, was auch immer dir widerfährt (better: widerfahren möge)"

Unfortunately an old contribution...

By the way: The sketch, reproduced by you, is very humorous.

A further problem solved...
