Judah, you are he whom your brothers shall praise … Judah is a lion's whelp... The scepter shall not depart from Judah, Nor a lawgiver from between his feet, Until shiloh comes; And to Him shall be the obedience of the people.
Genesis 49:8-10

But one of the elders said to me, "Do not weep. Behold, the Lion of the tribe of Judah, the Root of David, has prevailed to open the scroll and to loose its seven seals."
Revelation 5:5
