Jeremiah 31:32 (a) GOD uses this type to illustrate His deep love for Israel, and His devotion to their needs. He protected them, preserved them, and provided for them. Instead of a response from their hearts of loving affection, they turned against Him to worship idols. (See also Hosea 2:2).
2 Corinthians 11:2 (a) By this we understand the relationship of the Lord JESUS to those who are saved by His grace, and who constitute His bride.
