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.

Micah 6:6-8
6
How shall I come before Yahweh, and bow myself before the exalted God? Shall I come before him with burnt offerings, with calves a year old?
7
Will Yahweh be pleased with thousands of rams? With tens of thousands of rivers of oil? Shall I give my firstborn for my disobedience? The fruit of my body for the sin of my soul?
8
He has shown you, O man, what is good. What does Yahweh require of you, but to act justly, to love mercy, and to walk humbly with your God?
