If, as some have supposed, that the word Migdol-Eder, which we translate Tower, means Bethlehem, and the very place where the Jewish shepherds were keeping their flocks by night, when the angels announced to them the birth of Christ. Luke 2:8-9. there is an uncommon beauty in this passage in reference to Christ. Certain it is that the Church is Christ's flock, and Christ himself as a tower of defense, See Zechariah 9:12 and Ezekiel 34:31. And it may be truly said, that Christ's kingdom began from thence, when Christ was born in Bethlehem king of the Jews, Matthew 2:2. Here also, in the travailing pains spoken of, is an allusion to the Church's first going into Babylon, and from thence being delivered.

9 Now why dost thou cry out aloud? is there no king in thee? is thy counsellor perished? for pangs have taken thee as a woman in travail.
10 Be in pain, and labour to bring forth, O daughter of Zion, like a woman in travail: for now shalt thou go forth out of the city, and thou shalt dwell in the field, and thou shalt go even to Babylon; there shalt thou be delivered; there the LORD shall redeem thee from the hand of thine enemies.
