This first example of the Hebrew term for “God” makes a simple mistake of confusing Hebrew characters that look similar (of which there are a few!). The bottom letter on the tattoo is a samech (a Hebrew “s”) while it is supposed to be a mem (a Hebrew “m”). Another possibility that Yitzhak Sapir noted in the comments, is that the final letter is the Rashi script for final mem. He suggests that “some Jewish figure who was uncomfortable writing out the name of God changed scripts as a result.” While this is certainly possible, it seems odd that the rest of the tattoo is standard Aramaic square script. I am also not sure how many Jewish tattoo artists are out there who know Rashi’s script! I think my explanation makes a bit more sense. This tattoo is an example of a simple mistake made by someone who was trying to match the letters from a picture or something (I get quite a few papers from students who know a little Hebrew and try to include Hebrew words but they confuse stuff like final mem and samech, resh and dalet, etc.). Either way, if you are going to get a tattoo, it’s probably better to use the same script for the entire thing!
This tattoo, which has a Hebrew word purported by the website I found it on to mean “freedom” (perhaps based on Lev 19:20?) has the vowel points shifted incorrectly to the left. As such it is nonsensical. Moreover, as the comments to this post indicate, in modern Hebrew this word (if correctly pointed) means “vacation” — which I am pretty sure the individual who got the tattoo did not want (especially considering the symbol of the Holy Spirit above it!).
This tattoo, which means “holy to the LORD/Yahweh,” has letters which are either not drawn very carefully or confused (note the difference in width in the second last character in the bottom word; the tattoo has what looks like a dalet or resh, which it should be a vav) as well as incorrect vowel pointing.
This tattoo is supposed to say “in blood” according to the website where I found it. The expression is not biblical Hebrew, but a modern Hebrew phrase for “blood relative” or the like (see the comments by Yitzhak Sapir). Of course, the tattoo is still incorrect since it is missing the silent sheva after the resh (and the resh looks a bit like a yod). (If I was going to write “in blood” in Biblical Hebrew, I would simply do it as I have it on the bottom.)
This tattoo of the name of the God of Israel, “Yahweh,” is fine, though the web page identified it as Aramaic. In fact, this is a paleo-Hebrew script of the divine name.
There is nothing wrong with this Hebrew tattoo. I just thought it’s funny because the word inscribed can possibly mean both “love” as well as “leather” (some scholars suggest that there is a homograph which means “leather” [see KB3]). It arguably occurs in Hosea 11:4 [perhaps] and Song 3:10 [more likely]). Perhaps this can be taken as a warning not to spend too much time in the tanning salons?! (Of course, in modern Hebrew it clearly means love, and as I already noted, there is nothing wrong with this tattoo.)
The lesson here is that you cannot trust pictures of Hebrew tattoos on the internet! Make sure to double check the spelling of the Hebrew word you want tattooed!
