Charles Spurgeon Commentary Jeremiah 31:3-4

"Jehovah appeared of old unto me, [saying], Yea, I have loved thee with an everlasting love: therefore with lovingkindness have I drawn thee. Again will I build thee, and thou shalt be built, O virgin of Israel: again shalt thou be adorned with thy tabrets, and shalt go forth in the dances of them that make merry." — Jeremiah 31:3-4 (ASV)

Jerusalem was all broken down, her houses were vacant, and her palaces were in ruins, but God's promise to her was, Again I will build thee, and thou shalt be built.
