Well, if you're looking for a good time, you won't be finding it in Exodus 13. In this chapter, God tells the Israelites that every first born of their livestock is to be dedicated to Him. He also commands them to observe the Passover and to celebrate the Feast of Unleavened Bread. Oh, and if that wasn't enough, He also says that every firstborn son of the Israelites should be dedicated to Him too. So, basically, when it comes to partying in Exodus 13, God is the only one having a good time.
