Plato, Laws 901d

οἱ θεοὺς μὲν ἀμφότεροι ὁμολογοῦντες εἶναι, παραιτητοὺς δὲ ἅτερος, ὁ δὲ ἀμελεῖς τῶν σμικρῶν. πρῶτον μὲν θεοὺς ἀμφότεροί φατε γιγνώσκειν καὶ ὁρᾶν καὶ ἀκούειν πάντα, λαθεῖν δὲ αὐτοὺς οὐδὲν δυνατὸν εἶναι τῶν ὁπόσων εἰσὶν αἱ αἰσθήσεις τε καὶ ἐπιστῆμαι· ταύτῃ λέγετε ἔχειν ταῦτα, ἢ πῶς; οὕτως. τί δέ; δύνασθαι πάντα ὁπόσων αὖ δύναμίς ἐστιν θνητοῖς τε καὶ ἀθανάτοις; πῶς γὰρ οὐ συγχωρήσονται καὶ ταῦτα οὕτως ἔχειν;

First, you both assert that the gods know and hear and see all things, and that nothing of all that is apprehended by senses or sciences can escape their notice; do you assert that this is so, or what? That is what we assert. And further, that they can do all that can be done by mortal or immortal? They will, of course, admit that this also is the case.
