Covenant

But this is the covenant which I will make with the house of Israel: After those days, says the Lord, I will put My law within them, and on their hearts will I write it; and I will be their God, and they will be My people. And they will no more teach each man his neighbor and each man his brother, saying, Know the Lord, for they will all know Me [recognize, understand, and be acquainted with Me], from the least of them to the greatest, says the Lord. For I will forgive their iniquity, and I will [seriously] remember their sin no more.
