These seem to be the words of the Jewish church to Christ: O Lord, by thy grace I am what thou wouldst have my sister to be, a wall, and therefore do humbly beg and hope that, according to thy promise to her in that case, thou wilt build upon me a palace of silver.
My breasts like towers; which stand out from and above the wall, and are an ornament and defence to it. Of the church’s breasts, see before, Son_4:5 7:3,7.
Then was I in his eyes as one that found favour; when by his grace I was made a wall, he was well-pleased with me, and with his own workmanship in me.
