My pastor said that in that day (which I need to look into) that for the dead to bury the dead, it might have taken a whole year.
Wherever you're attending, in whatever church building where you have this pastor teaching... I would highly recommend getting out of there. Here's why:And if a man have committed a sin worthy of death, and he be to be put to death, and thou hang him on a tree: His body shall not remain all night upon the tree, but thou shalt in any wise bury him that day; (for he that is hanged is accursed of God;) that thy land be not defiled, which the LORD thy God giveth thee for an inheritance.
The Jews never waited a year to bury the dead, and you can see this logically in the verse. The only reason they would not have buried the hanged man immediately, as they did with everyone else, was to make an example of him for all those who passed through. However, God said not to do that, otherwise, the dead corpse would defile the land (i.e. because of spiritual violations, and through disease).
The reason I say to get away from that man is because he's teaching from a standpoint of worldly knowledge, or in other words, he's looking to worldly traditions to explain the Word of God first and foremost, rather than going to the Bible itself. I could be wrong about that, but I'm not aware of anything in Scripture that talks about them waiting a year to bury their dead. He didn't bother to go back to the Bible and find out what the standard operating procedure was, and it almost sounds like he got that from someone's commentary.
Israel still buries their dead to this day. Only those who were wealthy had tombs, and even then, they were placed in the tombs as soon as they died... they didn't keep them around for a while first. Sure, they might have been around a day or two for the family to come and grieve, but making up a story about how Jesus didn't want them to wait a year is an idea pulled out of thin air. (Or in the pastor's case, it might be hot air.)
