“Whoever swears
By the altar,
Swears by it
And everything on it.
Whoever swears
By the Temple,
Swears by it
And the one
Who dwells in it.
Whoever swears
By heaven,
Swears by the throne
Of God
And by the one
Who sits upon it.”
ὁ οὖν ὀμόσας ἐν τῷ θυσιαστηρίῳ ὀμνύει ἐν αὐτῷ καὶ ἐν πᾶσι τοῖς ἐπάνω αὐτοῦ·
καὶ ὁ ὀμόσας ἐν τῷ ναῷ ὀμνύει ἐν αὐτῷ καὶ ἐν τῷ κατοικοῦντι αὐτόν·
καὶ ὁ ὀμόσας ἐν τῷ οὐρανῷ ὀμνύει ἐν τῷ θρόνῳ τοῦ Θεοῦ καὶ ἐν τῷ καθημένῳ ἐπάνω αὐτοῦ
This is unique to Matthew. Jesus remarked that whoever swore by the altar (ὁ οὖν ὀμόσας ἐν τῷ θυσιαστηρίῳ), also swore by it and everything on it (ὀμνύει ἐν αὐτῷ καὶ ἐν πᾶσι τοῖς ἐπάνω αὐτοῦ). Whoever swore by the Temple (καὶ ὁ ὀμόσας ἐν τῷ ναῷ), also swore by it and the one who dwelt in the Temple (ὀμνύει ἐν αὐτῷ καὶ ἐν τῷ κατοικοῦντι αὐτόν). Whoever swore by heaven (καὶ ὁ ὀμόσας ἐν τῷ οὐρανῷ), swore by the throne of God (ὀμνύει ἐν τῷ θρόνῳ τοῦ Θεοῦ) and God himself who sits on it (καὶ ἐν τῷ καθημένῳ ἐπάνω αὐτοῦ). Thus, Jesus pulled together the fact that the altar, the Temple, and heaven itself were related to the presence of God.
