Micah 6:5
My people, remember what Balak king of Moab counseled and what Balaam son of Beor answered. Remember your journey from Shittim to Gilgal, that you may know the righteous acts of the LORD.
When I read this, I did remember the story of Balak and Balaam (you can read it in Numbers 22 for a refresher.) Balak, the king of Moab, sought out Balaam, a prophet, to prophesy victory for the Moabites over the Israelites in battle (this was during their first journey to the promised land.) God, however, would not allow Balaam to speak any false prophecy, and he instead prophesied victory for the Israelites, much to the frustration of Balak, the lesson being that the Word of God is true and that the will of God cannot be changed by any man, prophet or not.
On the other hand, when I tried to remember the “journey from Shittim to Gilgal,” I didn’t have a clue what God was talking about!
