I received the following question:

Phil 3:20 For our conversation is in heaven; from whence also we look for the Saviour, the Lord Jesus Christ:

In this passage you say that “heaven” is plural.

How did you know that this is a plural word?

Greek is en ouranois.

En typically takes the dative case.

Singular dative would be ouranoi

Plural dative is ouranois

Thus this is plural.

If you are wondering if the “s” makes it plural in Greek, that is just in this case. This varies by gender and by type of noun. Often it is NOT “s” that makes something plural in Greek. That is just a coincidence in this case. There is no standard for what makes something plural in Greek, as there is in English (“s”) or in Hebrew (“im”).

Hope that helps. You are welcome!
