Ezekiel 24:18 - Matthew Poole's English Annotations on the Holy Bible

I spake unto the people; told them what God had told me, and which I expected would be. In the morning; it is likely he had this revelation in the night, or evening before, and he tells them betimes in the morning, what God would do in taking away his wife, and what he must not do when she is dead, and to be buried. The next morning after her death he observed God's command, and without any sign of sorrow or mourning for his great loss.
