Genesis 49:9-10

9 Judah is a lion's whelp; from the prey, my son, you have gone up. He crouches down, he stretches out like a lion, like a lioness—who dares rouse him up?
10 The scepter shall not depart from Judah, nor the ruler's staff from between his feet, until tribute comes to him; and the obedience of the peoples is his.
