Yahweh, via Micah, wanted his people to remember his saving acts when they first came to Canaan. They were to remember King Balak of Moab and his interaction with the prophet Balaam, as in Numbers, chapters 22-24, when they were first approaching Canaan. Then they were also to remember what happened between Shittim and Gilgal. Gilgal was the first camp in Canaan, while Shittim was the last camp in their invasion of this country, as outlined in Numbers, chapter 25. Remembering these events was very important.
Yahweh, via Hosea, spoke to all the people of Israel. He told the priests to listen. He wanted the people of Israel and the royal household to listen also. This judgement pertained to all of them. They had been a snare at Mizpah, the Transjordan city, north of Jerusalem. They had also spread their net over Tabor, Mount Tabor, where there was an idol sanctuary also. They had dug a deep pit at Shittim, where there was religious intermarriage. Yahweh was going to punish them for these anti-Yahweh activities.
