Hi Leaf473,
This is a really bad misuse of Exodus 16 in order to have it supposedly validate the idea of "a Sabbath day's journey." Have you taken a moment to consider the implications of the imposition on Exodus 16:29? I believe that SabbathBlessings has already called your attention to the context and it seems that in your response here that you're just waving your hand dismissively, not caring how the context explicitly ties this text to the collection of manna. Instead you are doing as I suggested previously and are looking to the uninspired hedges erected by the Jews in their zeal to protect the Sabbath. Ignoring the context is a bad sign of your willingness to rightly handle the word of God. But let's set that aside for a moment and look at the text in question again and see if you can adjust your current paradigm.
Exodus 16:29
See! For the Lord has given you the Sabbath; therefore He gives you on the sixth day bread for two days. Let every man remain in his place; let no man go out of his place on the seventh day.”
Certainly there isn't anything here about traveling on a journey, let alone a journey lasting a day, or something more strictly concerned with a specific distance. In the Encyclopedia of the Bible they indicate that the "distance has been generally reckoned as 2000 cubits or approximately 2/3 of a mile.
Acts 1:12, the only instance of its occurrence in the Bible, specifies its length as the distance from Mt. Olivet to Jerusalem." You can see that Exodus 16:29 doesn't provide for this 2000 cubits distance. However, if one were to do you are doing and strip this text of its context then a strict reading would indicate that no one could leave their place, period (You already alluded to the idea of no one leaving their place to go to the restroom, but then automagically turned around and allowed for that). But the truth of this text can be found in the story of the Sabbath breaker who was put to death for gathering wood on the Sabbath.
Numbers 15:32-36
While the Israelites were in the wilderness, a man was found gathering wood on the Sabbath day. Those who found him gathering wood brought him to Moses and Aaron and the whole assembly, and they kept him in custody, because it was not clear what should be done to him. Then the Lord said to Moses, “The man must die. The whole assembly must stone him outside the camp.” So the assembly took him outside the camp and stoned him to death, as the Lord commanded Moses.
This man was not sentenced to death for leaving his place on the Sabbath. Indeed, neither was there guilt found for those who found this man gathering wood and who brought him to Moses and Aaron. Furthermore, there was no issue in the fact that God sent the whole assembly OUTSIDE THE CAMP to stone the man. That's a whole lotta "traveling" going on.
I pray this helps.
But for the grace of God go I,cyspark
