'Suffering' in the Bible

Then they sat on the ground with him seven days and nights, but no one spoke a word to him because they saw that his suffering was very intense.

For you will forget your suffering,recalling it only as waters that have flowed by.

Even if I speak, my suffering is not relieved,and if I hold back, what have I lost?

Now my life is poured out before my eyes,and days of suffering have seized me.

I am churning within and cannot rest;days of suffering confront me.
