These are great words from a great book: The Unfolding Mystery by Edmund Clowney. This is a short commentary on Genesis 49:9-10.
“The ancient prophecy is recalled again in the last book of the Bible. John weeps because there is no one who can open the book of God’s decrees. One of the elders in the heavenly throne room responds, ‘Do not weep! See, the Lion of the tribe of Judah, the Root of David, has triumphed. He is able to open the scroll and its seven seals’ (Rev. 5:5).”
“Jesus, the Lion of Judah, is also the Lamb that was slain. He who is the Lord came as the Servant. There is more than a chance similarity between the sign of Joseph and the fulfillment in Jesus. Deep in the structure of God’s redemptive plan is the principle that His power is made perfect in weakness. Not by human might, but by the power of God’s Spirit, the promises of His word are fulfilled. God’s chosen Ruler is His Suffering Servant, betrayed by His brethren but raised up to fulfill God’s promise.”
