Hosea said that the prophet should be a sentinel or watchman for God over the territory of Ephraim. However, the bird hunter or fowler had set snares for them. There was so much hostility in the house of God. They simply corrupted themselves too much. It was like in the days of Gibeah, as found in the situation over the concubine at Gibeah, in Judges, chapters 19-21. Then Hosea repeated what he had said in the preceding chapter that Yahweh would remember their iniquity, so that he would punish them for their sins.
The people living today on this earth have not learned the way to knowledge. They have not understood the various paths to get there. They are unable to grab knowledge. Their descendants have wandered far off the beaten path towards knowledge. Thus they cannot hear or see of knowledge in Canaan or Teman. Canaan was the old name for the land of Israel, while Teman was a city in Edom, south of Israel that was well known for its wisdom. The descendants of Hagar, the concubine of Abraham, or the Ishmaelites, were also seeking understanding. However, the merchants of Midian or Merran with the merchants of Teman in Edom have not learned the various paths to wisdom. The story-tellers and even those seeking understanding have not learned the way or path to wisdom. In fact, they have given little thought to this question.
