Lamentations 2:18 In-Context

16 AIN. All thine enemies have opened their mouth against thee: they have hissed and gnashed their teeth, and said, We have swallowed her up: moreover this is the day which we looked for; we have found it, we have seen it.
17 PHE. The Lord has done that which he purposed; he has accomplished his word, the things which he commanded from the ancient days: he has thrown down, and has not spared: and he has caused the enemy to rejoice over thee, he has exalted the horn of him that afflicted thee.
18 TSADE. Their heart cried to the Lord, Ye walls of Sion, pour down tears like torrents day and night: give thyself no rest; let not the apple of thine eyes cease.
19 KOPH. Arise, rejoice in the night at the beginning of thy watch: pour out thy heart as water before the face of the Lord; lift up thy hands to him for the life of thine infants, who faint for hunger at the top of all the streets.
20 RHECHS. Behold, O Lord, and see for whom thou has gathered thus. Shall the women eat the fruit of their womb? the cook has made a gathering: shall the infants sucking at the breasts be slain? wilt thou slay the priest and prophet in the sanctuary of the Lord?
