'Sorrow' in the Bible

And [when he] got up from the prayer [and] came to the disciples, he found them sleeping from sorrow,

But because I have said these [things] to you, sorrow has filled your hearts.

Truly, truly I say to you, that you will weep and lament, but the world will rejoice; you will become sorrowful, but your sorrow will change to joy.

So you also are experiencing sorrow now, but I will see you again, and your hearts will rejoice, and no one will take away your joy from you.

For I have decided this for myself, not to come to you again in sorrow.

For if I [cause] you sorrow, then who will make me glad except the one who is caused to be sad by me?

And I wrote this very [thing] in order that [when I] came, I would not experience sorrow from those who ought to have made me glad, [because I] have confidence about you all, that my joy {belongs to all of you}.

But if anyone has caused sorrow, he has not caused me sorrow, but {to some degree}--{in order not to say too much}--[to] all [of] you.

So then, you should rather forgive and comfort him, lest somehow this person should be overwhelmed by excessive sorrow.
