According to Torah law, Jewish people are prohibited from getting tattoos. The source of this prohibition is Leviticus 19:28, which states: “You shall not etch a tattoo on yourselves.” This restriction applies to all tattoos, with an exception made only for medical purposes, such as to guide a surgeon making an incision.
Although some of the commentaries1 seem to believe that this is one of the Torah’s chukim, the commandments whose rationales transcend the ken of human intellect, other commentators do offer several explanations for this prohibition:
- The human body is G‑d’s creation, and it is therefore unbefitting to mutilate G‑d’s handiwork. It is especially unbefitting for members of G‑d’s chosen nation to mutilate their bodies. One must believe that G‑d, the greatest artisan of all, formed him or her in the most fitting way, and one must not change this form. Changing one’s body (unless it is for health reasons) is tantamount to insulting G‑d’s handiwork.2
- In ancient times, it was customary for idol-worshippers to tattoo themselves as a sign of commitment to their deity—much like an animal that is branded by its owner. On many occasions the Torah forbids practices that emulate pagan customs, considering that following their traditions is the first step towards subscribing to their idolatrous beliefs and services.3
- The covenant of circumcision is unique in its being a sign in our bodies of our relationship with G‑d. Making other signs in one’s body would weaken and cheapen this special sign.4

In a previous lost life of sadness and confusion, and lacking a serious relationship with G-d I was foolish and got a tattoo on my right arm and my left ankle. It looks so out of place now. Going through the process of returning to my faith, I wonder; where do I stand? Of course I regret my tattoos! I contemplated getting them for over ten years and as soon as I did I thought - - my skin is already a piece of art, G-d's art! It doesn't need foreign work on in.
What are the consequences for someone like me?
Not every consequence is spelled out in the Torah. Yet, the very fact that you sincerely regret this - is what truly matters to G-d. G-d always accepts our Teshuvah - return to Him. As long as we sincerely regret the past, and choose to be better in the future, G-d forgives our past transgressions.
Blake, hi. You seem to think a tattoo is the worst of crimes. According to Maimonides there are 613 commandments, Such as, not to be afraid to kill a false prophet, not to read your horoscope and not to paint or draw a portrait or human figure. Why on earth do you think having a tattoo is worse than the other 612 commandments?
As one like Blake , who has foolishly tattooed himself , I understand his concern. You can forget many mistakes and move on but this one is there for you to see every day. I was told not to do it but I was a fool and did not listen. I see my foolishness and stupidity every day.
But G-d forgives, just tell Him you regret it, if it troubles you.
