'Plaint' in the Bible

Attend unto me, and answer me: I wander about in my plaint, and I moan aloud,

{To the chief Musician. A Psalm of David.} Hear, O God, my voice in my plaint; preserve my life from fear of the enemy:

A Prayer of the afflicted when he is feeble, and before Jehovah poureth out his plaint. O Jehovah, hear my prayer, yea, my cry to Thee cometh.

I pour out my plaint before him; I shew before him my trouble.
