When there is a compound subject, the verb often agrees with the nearest one. In this construction, the verb usually precedes the subjects or stands directly after the first of them.
|Μὴ θησαυρίζετε ὑμῖν θησαυροὺς ἐπὶ τῆς γῆς, ὅπου σὴς καὶ βρῶσις ἀφανίζει καὶ ὅπου κλέπται διορύσσουσιν καὶ κλέπτουσιν
|“Do not lay up for yourselves treasures on earth, where moth and rust destroy and where thieves break in and steal…
σὴς and βρῶσις are.
