To whom shall I speak, and give warning, that they may hear? behold, their ear is uncircumcised, and they cannot hearken: behold, the word of the LORD is unto them a reproach; they have no delight in it.
To whom should I talk and warn so they can listen? But they can't, because their ears aren't able to hear. They don't like God's word; it's embarrassing to them and brings them no joy.
