How do we know Jacob's messages were inspired by God?

The inspiration of Jacob's messages is affirmed by their inclusion in the sacred Scripture, which holds that all Scripture is God-breathed. In 2 Peter 1:21, it is made clear that men of God spoke as they were moved by the Holy Spirit, indicating that Jacob's utterances were not mere reflections of his thoughts, but revelations from God. The very nature of prophecy, as described in Scripture, involves God communicating His truths through chosen vessels. Therefore, the prophetic character of Jacob's words in Genesis 49 underscores their divine origin, contributing to their authority and timeless application for the church today. The fulfillment of these prophecies in the life of Judah and his descendants, notably culminating in the person of Christ, further affirms their inspired nature.
