30 Take a good heart, O Jerusalem: for he that gave thee that name will comfort thee.

Baruch 4:30 In-Context

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.
