O my people!,
I will admonish you!
If you would but listen to me!
There shall be no strange god among you.
You shall not bow down to a foreign god.
I am Yahweh!
I brought you up out of the land of Egypt.
Open your mouth wide!
Then I will fill it.”
Yahweh speaks, probably through the Temple prophet. He wanted to admonish his people, Israel. If only they would listen to him. Very clearly he says that there should not be any strange gods among them. They were not to bow down to foreign gods. He was Yahweh, their God. He brought them out of Egypt. He wanted them to open their mouths wide so that he could fill them.
