A traditional Jewish Passover meal incorporated four cups, one for each of the promises the LORD made before He brought the nation of Israel out of Egypt:
Therefore, tell the Israelites, ‘I am the LORD. I will bring you out from your enslavement to the Egyptians, I will rescue you from the hard labor they impose, and I will redeem you with an outstretched arm and with great judgments. I will take you to myself for a people, and I will be your God. Then you will know that I am the LORD your God, who brought you out from your enslavement to the Egyptians. (Exodus 6:6-7 NET)
In the messages to the seven churches in Asia, the overcomer in each church is given a promise. Those in Philadelphia are told:
The one who conquers I will make a pillar in the temple of my God, and he will never depart from it. I will write on him the name of my God and the name of the city of my God (the new Jerusalem that comes down out of heaven from my God), and my new name as well. (Revelation 3:12 NET)
Does the grammar of the text support seeing the promise as made up of four separate items?
Ὁ νικῶν ποιήσω αὐτὸν στῦλον ἐν τῷ ναῷ τοῦ θεοῦ μου καὶ ἔξω οὐ μὴ ἐξέλθῃ ἔτι καὶ γράψω ἐπ’ αὐτὸν τὸ ὄνομα τοῦ θεοῦ μου καὶ τὸ ὄνομα τῆς πόλεως τοῦ θεοῦ μου, τῆς καινῆς Ἰερουσαλὴμ ἡ καταβαίνουσα ἐκ τοῦ οὐρανοῦ ἀπὸ τοῦ θεοῦ μου, καὶ τὸ ὄνομά μου τὸ καινόν. (NA28)
