'Undisciplined' in the Bible

The rod and reproof (godly instruction) give wisdom,But a child who gets his own way brings shame to his mother.

Moreover, the Lord said, “Because the daughters of Zion are proudAnd walk with outstretched necks and seductive (flirtatious, alluring) eyes,And trip along with mincing steps and an affected gaitAnd walk with jingling anklets on their feet,

But no one can tame the human tongue; it is a restless evil [undisciplined, unstable], full of deadly poison.
