Sigh therefore, thou son of man, with the breaking of [thy] loins; and with bitterness sigh before their eyes. (21:6)

And it shall be, when they say unto thee, Wherefore sighest thou? that thou shalt answer, For the tidings; because it cometh: and every heart shall melt, and all hands shall be feeble, and every spirit shall faint, and all knees shall be weak [as] water: behold, it cometh, and shall be brought to pass, saith the Lord GOD. (21:7)
