Riphath
In Genesis 10:3, 'Riphath' was one of several nations which had an external form of worship, and signifies several doctrinal matters, which respected ritual observances derived from the external worship of Gomer. This is clear from the Prophets where the same nations are mentioned again. Those nations represent doctrinal teachings or forms of ritual.

Stay
In Genesis 8:10, this signifies the period between two states. (Arcana Coelestia 880)
'To stay with,' as in Genesis 32:4, relates to the life of truth when accompanied by good, and in this instance, it means to take something in.
