'Hearts' in the Bible

"Do not harden your hearts as in the rebellion, in the day of testing in the wilderness.

"Therefore, I became provoked at that generation and said, 'Their hearts are always wandering and they have not known my ways.'

As it says, "Oh, that today you would listen as he speaks! Do not harden your hearts as in the rebellion."

So God again ordains a certain day, "Today," speaking through David after so long a time, as in the words quoted before, "O, that today you would listen as he speaks! Do not harden your hearts."

"For this is the covenant that I will establish with the house of Israel after those days, says the Lord. I will put my laws in their minds and I will inscribe them on their hearts. And I will be their God and they will be my people.

"This is the covenant that I will establish with them after those days, says the Lord. I will put my laws on their hearts and I will inscribe them on their minds,"

let us draw near with a sincere heart in the assurance that faith brings, because we have had our hearts sprinkled clean from an evil conscience and our bodies washed in pure water.
