Jeremiah 8:4-7

Moreover thou shalt say unto them, Thus saith Jehovah: Shall men fall, and not rise up again? Shall one turn away, and not return? Why then is this people of Jerusalem slidden back by a perpetual backsliding? they hold fast deceit, they refuse to return. I hearkened and heard, but they spake not aright: no man repenteth him of his wickedness, saying, What have I done? every one turneth to his course, as a horse that rusheth headlong in the battle. Yea, the stork in the heavens knoweth her appointed times; and the turtle-dove and the swallow and the crane observe the time of their coming; but my people know not the law of Jehovah.
