'Hearts' in the Bible

do not harden your hearts as your forefathers did in the time of the provocation on the day of the temptation in the Desert,

seeing that the warning still comes to us, "To-day, if you hear His voice, do not harden your hearts as your forefathers did in the time of the provocation."

He again definitely mentions a certain day, "To-day," saying long afterwards, by David's lips, in the words already quoted, "To-day, if you hear His voice, do not harden your hearts."

But this is the Covenant that I will covenant with the house of Israel after those days,' says the Lord: I will put My laws into their minds and will write them upon their hearts. And I will indeed be their God and they shall be My People.

"'This is the Covenant that I will make with them after those days,' says the Lord: 'I will put My laws upon their hearts and will write them on their minds;'"

let us draw near with sincerity and unfaltering faith, having had our hearts sprinkled, once for all, from consciences oppressed with sin, and our bodies bathed in pure water.
