John Wesley on Genesis 49:8

Judah's name signifies praise, in allusion to which he saith, Thou art he whom thy brethren shall praise, God was praised for him, Gen 29:35, praised by him, and praised in him; and therefore his brethren shall praise him. Thy hand shall be in the neck of thine enemies - This was fulfilled in David, Psa 18:40. Thy father's children shall bow down before thee - Judah was the law - giver, Psa 60:7. That tribe led the van through the wilderness, and in the conquest of Canaan, Jud 1:2. The prerogatives of the birth - right which Reuben had forfeited, the excellency of dignity and power, were thus conferred upon Judah. Thy brethren shall bow down before thee, and yet shall praise thee, reckoning themselves happy in having so wise and bold a commander.
