In fairness I should acknowledge that some decrees from God are short term only. Eating manna is one example, no specified expiry date but nevertheless impermanent. Another example is getting water from a rock. Initially Exodus 17:6 smiting the rock was commanded to obtain water. That didn't mean that whenever water was required a rock should be smitten to get it. Later on, thirst loomed again but this time Numbers 20:8 God's commandment was to speak to the rock. Moses did the wrong thing Numbers 20:11-12 and was punished accordingly. Food restrictions were similarly temporary, like eating manna or quails had been, and The Bible marks the end of those limitations unmistakably. Murder? Adultery? Mixed fabrics? Not so much. Those remain current.

When set free from slavery, The Israelites took a rather circuitous route not because they'd gone mad (they had at one stage gone mad, with the golden calf made from all that jewellery Exodus 12:35-36 purloined from the Egyptians at some considerable risk, given that they'd want it back eventually) but because they were guided by a pillars of fire & smoke Nehemiah 9:12 showing them where to go. Later on, say in 600BC or 2021AD to pick a couple of dates at random, different routes would be appropriate or even any route you fancied (not possible at present of course) because the limited commandments about travel or water have expired. It's explicitly so, though. Murder etc., still on the books.
