Ezekiel 36:37

Though I have repeated so often my promise to return them, to rebuild, to multiply them, yet they shall know it is their duty to entreat it, to wait on me, and then I will give a merciful answer and do it. Thus Daniel prayed, when he knew the return was sure and near. Or else it may be thus; Above all this, or yet more than all this, I will be found of them when they do seek me: thus it is a promise made to their prayer, in the other it is a requiring them to pray, so they shall increase as a flock.
