This oath is still being used and is still taken at some universities by graduates in medicine. It says:
I will look upon him who shall have taught me this art even as one of my parents. I will share my substance with him, and I will supply his necessities, if he be in need. I will regard his offspring even as my own brethren, and I will teach them this art, if they would learn it, without fee or covenant. I will impart this art by precept, by lecture and by every mode of teaching, not only to my own sons but to the sons of him who has taught me, and to disciples bound by covenant and oath, according to the law of medicine.
The regimen I adopt shall be for the benefit of my patients according to my ability and judgment, and not for their hurt or for any wrong. I will give no deadly drug to any, though it be asked of me, nor will I counsel such, and especially I will not aid a woman to procure abortion. Whatsoever house I enter, there will I go for the benefit of the sick, refraining from all wrongdoing or corruption, and especially from any act of seduction, of male or female, of bond or free. Whatsoever things I see or hear concerning the life of men, in my attendance on the sick or even apart therefrom, which ought not to be noised abroad, I will keep silence thereon, counting such things to be as sacred secrets.
The oath was contained in the Hippocratic Collection, a compilation of Greek medical writing assembled in the fourth century B.C. Hippocrates is said to have imposed the oath on his disciples.
We can't apply to this 2400-year-old oath what Steme says: "The Accusing Spirit, which flew up to heaven's chancery with the oath, blushed as he gave it in—and the Recording Angel, as he wrote it down, dropped a tear upon the word and blotted it out forever."
