'Grief' in the Bible

So they sat down on the ground with Job for seven days and seven nights and no one spoke a word to him, for they saw that his pain was very great.

“Oh, that my grief could actually be weighedAnd placed in the balances together with my tragedy [to see if my grief is the grief of a coward]!

“My eye has grown dim (unexpressive) because of grief,And all my [body’s] members are [wasted away] like a shadow.
