Deuteronomy 33:19

17His glory is like the firstling of his bullock, and his horns are like the horns of unicorns: with them he shall push the people together to the ends of the earth: and they are the ten thousands of Ephraim, and they are the thousands of Manasseh.

18And of Zebulun he said, Rejoice, Zebulun, in thy going out; and, Issachar, in thy tents.

19They shall call the people unto the mountain; there they shall offer sacrifices of righteousness: for they shall suck of the abundance of the seas, and of treasures hid in the sand.

20And of Gad he said, Blessed be he that enlargeth Gad: he dwelleth as a lion, and teareth the arm with the crown of the head.

21And he provided the first part for himself, because there, in a portion of the lawgiver, was he seated; and he came with the heads of the people, he executed the justice of the LORD, and his judgments with Israel.
