The OT is as valid today as it was in the time of Jesus. Only we need to temper teaching with what has happened prophetically to change issues.
Lev_19:28 Ye shall not make any cuttings in your flesh for the dead, nor print any marks upon you: I am the LORD.
Lev_21:5 They shall not make baldness upon their head, neither shall they shave off the corner of their beard, nor make any cuttings in their flesh.
The Israelites were forbidden to engage in this practice, one that was common among some other ancient peoples. For example, there were times when the Egyptians tattooed the names or symbols of their deities on their breast or arms.
By complying with God’s law not to disfigure their bodies, the Israelites would have stood out as different from other nations.
The prohibition would also have impressed upon them a proper respect for the human body as God’s creation, to be used in honoring him. Ps 100:3; 139:13-16; Ro 12:1.
Since Jesus was a Jew he would not have had a tattoo, he would have been breaking God's law if he had a tattoo.
It says it right here that god will smear dung, which is animal shlt, all over your face if you get a tatoo-
"Behold, if thou gets tatoos on thy body, I the Lord will corrupt your seed, and spread dung upon your faces, even the dung of your solemn feasts; and one shall take you away with it." - Malachi 2:3
參考: dung definition-
dung /noun. excrement, especially of animals; manure.
There's no verse saying its wrong or right but there is verse saying your body is a temple but if you want to get tattoo thats your business hope this helps!
參考: Me a christian with a tongue ring and one tattoo
It doesn't say it anywhere in the bible but i believe it is a sin to get so many tattoos that it could damage your skin because your body is your temple.
EDIT: I mean if you know the bible, according to Christianity. I know religious people that have tattoos.
