'And Pharaoh looked back and went to his house' means thought and reflection based on falsities. This is clear from the meaning of 'looking back' as thought and reflection, for in the spiritual sense
'looking back' is not looking at something with one's eyes but looking mentally, thus thinking and reflecting; and from the meaning of 'Pharaoh's house' as falsity. For when 'Pharaoh' represents falsity
his 'house' has the same meaning; and therefore 'going to his house' means [turning to] falsities. And since these words mean thought and reflection based on falsities, the phrase about his not taking
this to heart follows. For a person whose thought is based on falsities does not take it to heart when the Divine warns him.
