8 do not harden your hearts as you did in the rebellion, during the time of testing in the wilderness,
10 That is why I was angry with that generation; I said, ‘Their hearts are always going astray, and they have not known my ways.’
12 See to it, brothers and sisters, that none of you has a sinful, unbelieving heart that turns away from the living God.
15 As has just been said: “Today, if you hear his voice, do not harden your hearts as you did in the rebellion.”
7 God again set a certain day, calling it “Today.” This he did when a long time later he spoke through David, as in the passage already quoted: “Today, if you hear his voice, do not harden your hearts.”
12 For the word of God is alive and active. Sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart.
10 This is the covenant I will establish with the people of Israel after that time, declares the Lord. I will put my laws in their minds and write them on their hearts. I will be their God, and they will be my people.
16 “This is the covenant I will make with them after that time, says the Lord. I will put my laws in their hearts, and I will write them on their minds.”
22 let us draw near to God with a sincere heart and with the full assurance that faith brings, having our hearts sprinkled to cleanse us from a guilty conscience and having our bodies washed with pure water.
9 Do not be carried away by all kinds of strange teachings. It is good for our hearts to be strengthened by grace, not by eating ceremonial foods, which is of no benefit to those who do so.
