Jeremiah 2:1

Go and cry in the ears of Jerusalem, saying, Thus saith the LORD; I remember thee, the kindness of thy youth, the love of thine espousals, when thou wentest after me in the wilderness, in a land that was not sown.

Israel was holiness unto the LORD, and the firstfruits of his increase: all that devour him shall offend; evil shall come upon them, saith the LORD.

Hear ye the word of the LORD, O house of Jacob, and all the families of the house of Israel:

Thus saith the LORD, What iniquity have your fathers found in me, that they are gone far from me, and have walked after vanity, and are become vain?
