Ezekiel 3:18-19 applies to the prophet Ezekiel, not to you or me. If your basis for your stance against tatoos is Matthew 5:19 then what about the dietary laws, the Sabbath, the commanded holy days, and etc. as well as what Paul, John, and James wrote concerning the Law?
James 2:10-13
10 For whoever keeps the whole law and yet stumbles in one point, he has become guilty of all. 11 For He who said, "Do not commit adultery," also said, "Do not commit murder." Now if you do not commit adultery, but do commit murder, you have become a transgressor of the law. 12 So speak and so act, as those who are to be judged by the law of liberty. 13 For judgment will be merciless to one who has shown no mercy; mercy triumphs over judgment. NAS
No man can live in total obedience to God's law as Paul laments in Romans 7.
