'Stronger' in the Bible

Though Judah became stronger than his brothers, and from him came the ruler, the birthright was Joseph's:)

And he said, If the Aramaeans are stronger and get the better of me, then come to my help; and if the children of Ammon get the better of you, I will come to your help.

But the king's word was stronger than Joab's. So Joab went out and went through all Israel and came to Jerusalem.
