'Promises of God' in the Bible

All these sons of Heman, the king’s seer, were given by the promises of God to exalt him, for God had given Heman fourteen sons and three daughters.

“In those days and at that time,” says the Lord, “the children of Israel will come, they and the children of Judah together; they will come up weeping [in repentance] as they come and seek the Lord their God [inquiring for and of Him].

For all the promises of God in him are yea, and in him Amen, unto the glory of God by us.

Is the law then against the promises of God? God forbid: for if there had been a law given which could have given life, verily righteousness should have been by the law.
