Thou didst say, Woe is me now! for the LORD hath added grief to my sorrow; I fainted in my sighing, and I find no rest.
I find no rest — Upon Baruch's reading the prophecies both he and Jeremiah were advised to hide themselves. This probably disturbed Baruch, and made him lament his condition.
 And seekest thou great things for thyself? seek them not: for, behold, I will bring evil upon all flesh, saith the LORD: but thy life will I give unto thee for a prey in all places whither thou goest.
Seek them not — Dost thou expect what none is like to meet with who feareth God? Upon all flesh - I am bringing calamities upon the whole nation.
