'Hard hearted' in the Bible

“If there is a poor person among you, one of your brothers within any of your gates in the land the Lord your God is giving you, you must not be hardhearted or tightfisted toward your poor brother.

If a man has a son who is hard-hearted and uncontrolled, who gives no attention to the voice of his father and mother, and will not be ruled by them, though they give him punishment:

And say to them, This son of ours is hard-hearted and uncontrolled, he will not give attention to us; he gives himself up to pleasure and strong drink.

The most soft and delicate of your women, who would not so much as put her foot on the earth, so delicate is she, will be hard-hearted to her husband and to her son and to her daughter;

They have become false, they are not his children, the mark of sin is on them; they are an evil and hard-hearted generation.
