How many miraculous births are in the Old Testament?

Answer 1

There are at least two births in the Old Testament which share similar circumstances, and based on these circumstances might be considered miraculous.

One is the birth of Isaac from Sarah, and the other is the birth of Samuel from Hannah. In both cases, the women have no capacity for bearing children. Sarah was beyond childbearing years (cf. Gn 17:17, Gn 18:11-12) and Hannah had been made barren. (cf. 1 Sam 1:5)

Both births are significant because they testify that in spite of seemingly impossible circumstances, God nevertheless is always faithful to the old covenant He established with Abraham. Namely that his descendants would be as numerous as the stars. (cf. Gn 15:1-6)

Both women can also be seen as a foreshadowing of the miraculous power that God would ultimately work in His new covenant through the Blessed Virgin Mary; i.e. Mary shares (though by free choice of abstinence from sexual relations) the same initial incapacity for bearing children. Nevertheless, God, by the power of the Holy Spirit Lk 1:26-38 and the fiat of Mary, overcomes this seemingly impossible circumstance to initiate the new covenant with the Virgin Birth of the long awaited Messiah, Jesus.
