Baruch 4:23-33

23 For I sent you out with mourning and weeping: but God will give you to me again with joy and gladness for ever.
24 Like as now the neighbours of Sion have seen your captivity: so shall they see shortly your salvation from our God which shall come upon you with great glory, and brightness of the Everlasting.
25 My children, suffer patiently the wrath that is come upon you from God: for thine enemy hath persecuted thee; but shortly thou shalt see his destruction, and shalt tread upon his neck.
26 My delicate ones have gone rough ways, and were taken away as a flock caught of the enemies.
27 Be of good comfort, O my children, and cry unto God: for ye shall be remembered of him that brought these things upon you.
28 For as it was your mind to go astray from God: so, being returned, seek him ten times more.
29 For he that hath brought these plagues upon you shall bring you everlasting joy with your salvation.
30 Take a good heart, O Jerusalem: for he that gave thee that name will comfort thee.
31 Miserable are they that afflicted thee, and rejoiced at thy fall.
32 Miserable are the cities which thy children served: miserable is she that received thy sons.
33 For as she rejoiced at thy ruin, and was glad of thy fall: so shall she be grieved for her own desolation.
