'Willful' in the Bible

"For the Lord has finished all his work against Mount Zion and against Jerusalem; he will punish the speech that comes from that willful heart of Assyria's king and the haughty look in his eyes.

“Because of the wickedness of his unjust gain I was angry and struck him;I hid My face and was angry,And he went on turning away and backsliding, in the way of his [own willful] heart.

“I have seen his [willful] ways, but I will heal him;I will lead him [also] and will restore comfort to him and to those who mourn for him,
