Thirty
'Thirty' has a twofold significance because it is is the product of five and six, and also three and ten. From five multiplied by six, it signifies some aspect of combat, because 'five' signifies some part or aspect, and 'six,' combat. From three multiplied by ten, it signifies something full of remains of good and truth, because 'three' signifies fullness, and 'ten,' remains of good and truth. A composite number involves the same as the simple numbers it has as its factors.

for the precious things of the earth and its fullness, the good will of him who lived in the bush. Let [the blessing] come on the head of Joseph, On the crown of the head of him who was separate from his brothers.

The firstborn of his herd, majesty is his. His horns are the horns of the wild ox. With them he shall push the peoples all of them, [even] the ends of the earth: They are the ten thousands of Ephraim. They are the thousands of Manasseh."
