Genesis 49:9

Judah is a lion's whelp; from the prey, my son, thou art gone up; he stooped down, he couched as a lion and as an old lion; who shall rouse him up? From his youth Judah had shown that he possessed the nature, the character of a lion, as a whelp, as a young lion, as a mature lion. Having caught his prey, the lion returns to his mountain fastnesses, into his den, where a person will attack him only at the risk of his own life. The tribe of Judah, forming the vanguard during the wilderness journey, settled on the highlands and mountains of Judea, grew to be a mighty tribe, gaining strength from the many defeats of its enemies, secure in its dominion.
