Exodus 8:18
Rahlfs Septuagint (1935) · Berean Standard Bible
καὶ παραδοξάσω ἐν τῇ ἡμέρᾳ ἐκείνῃ τὴν γῆν Γεσεμ ἐφ᾿ ἧς ὁ λαός μου ἔπεστιν ἐπ᾿ αὐτῆς ἐφ᾿ ἧς οὐκ ἔσται ἐκεῖ ἡ κυνόμυια ἵνα εἰδῇς ὅτι ἐγώ εἰμι κύριος ὁ κύριος πάσης τῆς γῆς
The magicians tried to produce gnats using their magic arts, but they could not. And the gnats remained on man and beast.
