'Wax' in the Bible

And my wrath shall wax hot, and I will kill you with the sword; and your wives shall be widows, and your children fatherless.

Now therefore let me alone, that my wrath may wax hot against them, and that I may consume them: and I will make of thee a great nation.

And Moses besought the LORD his God, and said, LORD, why doth thy wrath wax hot against thy people, which thou hast brought forth out of the land of Egypt with great power, and with a mighty hand?

And Aaron said, Let not the anger of my lord wax hot: thou knowest the people, that they are set on mischief.
