Jeremiah 2:2-3

2 Go and cry in the ears of Jerusalem, saying, Thus said the LORD; I remember you, the kindness of your youth, the love of your espousals, when you went after me in the wilderness, in a land that was not sown.

3 Israel was holiness to the LORD, and the first fruits of his increase: all that devour him shall offend; evil shall come on them, said the LORD.
