Face of the deep
The face of the deep (Genesis 1:2) signifies the lust of the unregenerate man, and the falsities that originate from it.
(References: Arcana Coelestia 018, Genesis 1)
Look
'Look not back behind thee,' as in Genesis 19:17, means that Lot, who represents the good of charity, should not look to matters of doctrine. 'To look up,' is to look to celestial things. In Genesis 18:22, looking signifies thinking because seeing denotes understanding.
