Early rabbinic interpretation connected the curse of child eating (Lev 26:29; Deut 28:53-57) with the description of the Babylonian destruction of Jerusalem in Lamentations (2:20 and 4:10) and the Roman destruction of the Second Temple. In the Middle Ages, however, Jewish commentators de-emphasize this connection. The reason for this may lie in the 12th c. development of Christian Bible commentary.

The First Temple was destroyed either on the 10th of Av (Jeremiah 52:12) or the 7th (2 Kings 25:8). The Second Temple, according to Josephus, was destroyed on the 10th. How did Rabbinic Jews come to commemorate the destruction of both Temples on the 9th of Av?
