'Promised' in the Bible

Let us hold on to the confession of our hope without wavering, for He who promised is faithful.

For you need endurance, so that after you have done God’s will, you may receive what was promised.

By faith even Sarah herself, when she was unable to have children, received power to conceive offspring, even though she was past the age, since she considered that the One who had promised was faithful.

All these were approved through their faith, but they did not receive what was promised,

His voice shook the earth at that time, but now He has promised, Yet once more I will shake not only the earth but also heaven.
