I recently watched A video on YouTube from Mark Biltz When Will the Tribulation Begin? Where are we on the BIBLICAL calendar? It is extremely informative and a MUST watch. I will try to sum up what he has taught in the video on the Shemitah year and cycles. I still recommend that you watch it, because I cannot go into as much detail as he did in this blog.
The Shemitah year is a Sabbath year, every 7th year is a Shemitah or Sabbath year where God commanded the Israelite’s to rest the land. Every 7 years is a Shemitah cycle. God told Israel that the land that they were to inherit needed to rest every 7 years because it was holy.
