Ezekiel 36:37-38

37‘Thus says the Lord God, “This too I will let the house of Israel ask Me to do for them: I will increase their people like a flock.

38Like the flock for sacrifices, like the flock at Jerusalem during her appointed feasts, so will the desolate cities be filled with flocks of people. Then they will know [with confident assurance] that I am the Lord.” ’ ”
