It means, I am your doctor, I am here to help, I will do whatever I can to support, and, with this the clinical contract – first, I will do no harm, second, this is confidential and, third, well, If I don’t know, I’ll find someone who does.
Relative: Doctor, I believe my mum is dying, I want us to stop the antibiotics/fluids/oxygen/etc.
Doctor: No, I feel we should continue, there might be some improvement (aka other blandishment/platitude).
Camerado, I give you my hand!
I give you my love more precious than money,
I give you myself before preaching or law;
Will you give me yourself? will you come travel with me?
Shall we stick by each other as long as we live?
