Ταξάμενοι δὲ αὐτῷ ἡμέραν ἦλθον πρὸς αὐτὸν εἰς τὴν ξενίαν πλείονες οἷς ἐξετίθετο διαμαρτυρόμενος τὴν βασιλείαν τοῦ θεοῦ, πείθων τε αὐτοὺς περὶ τοῦ Ἰησοῦ ἀπό τε τοῦ νόμου Μωϋσέως καὶ τῶν προφητῶν, ἀπὸ πρωῒ ἕως ἑσπέρας.It's traditional to see the OT as having had three divisions in Jesus' day: Law, Prophets, Writings. Here, we see two divisions. In Inspiration and Canonicity of the Scriptures, R. Laird Harris makes the case (convincingly, I think) that the OT was more characteristically seen under two divisions.
Notice τε twice. The first time it looks as if it coordinates the two ways in which Paul ἐξετίθετο, namely διαμαρτυρόμενος and πείθων.
The second time, we have τε...καὶ (both...and), coordinating the two divisions of the OT, and thus indicating the whole OT as Paul's range of texts.
