“The prophet is a watchman.” This verse is extremely difficult in Hebrew, and beyond that, there are variant texts. The difficulty is reflected in the different English translations. The translation in the REV is one possibility, that the prophet is to be a watchman for Yahweh, and yet in Hosea’s time there was hostility towards true prophets and traps laid for them.

“on behalf of my God.” This could also be “along with my God.”
