# they lifted up their eyes

"they looked intently" or "they looked carefully."

# they did not recognize him

"they barely recognized him". This probably means that Job's visitors did not recognize him at first. Job looked very different because of his grief and because of the sores covering his body.

# They raised their voices and wept

"They wept loudly"

# tore his robe and threw dust into the air and upon his own head

These were signs of mourning.
