Thy way and thy doings have procured these things unto thee; this is thy wickedness, yea, it is bitter, yea, it reacheth unto thy heart.

Thus saith Jehovah: A voice hath been heard in Ramah, the wail of very bitter weeping, Rachel weeping for her children, refusing to be comforted for her children, because they are not.
