God's prophets were called to speak his word rightly. But each, including Moses, was sinful and none spoke His word fully. Jesus is God's perfect prophet - speaking the words of eternal life (John 6:68-69). Whenever we read the Old Testament prophets, we ought to ask: Where does Jesus speak a similar but better word? This might require a good study Bible or at least a Bible with marginal references (ie. little numbers or letters with Scripture references attached - usually pointing you to the New Testament). I want to introduce you to an excellent resource. Both the online and the print versions of the ESV Study Bible has an amazing section in the back entitled - The History of Salvation in the Old Testament: Preparing the Way for Christ.
I have posted below from this section a selection screenshots of the OT prophets (including Isaiah, Jeremiah, Ezekiel, Hosea, Amos, Jonah, Zechariah). By looking through some of these and their corresponding references, you are training yourself for how to hear God's prophetic voice in the OT and connect it to an even better word spoken or fulfilled by Jesus.
