And where did Jesus ? He went to the Garden tomb, which can be translated paradise, he died, he rose and walked the earth for 40 more days before going to Heaven, so either Jesus lied to the thief or he was saying today you will die and end up buried. Which is what happened, the Jews wanted those crucified to be killed early because of the sabbath, so the soldiers broke the thieves legs , Jesus was already dead so his legs were not broken.
Explain what you mean by "He went to the Garden tomb, which can be translated paradise".
After Jesus' death it says He went to the bowels of the earth to preach to those in prison. The Bible talks about Sheoul/Hades that is divided into two camps where one side is considered "Paradise" and the other is considered Hell. They are separated by "a great chasm". Jesus may have taken the thief to Paradise and then preached to those in prison.
