Albert Barnes Commentary Job 22:29

"When they cast [thee] down, thou shalt say, [There is] lifting up; And the humble person he will save." — Job 22:29 (ASV)

When men are cast down - The meaning of this is, probably, when people are usually cast down, or in times of trial and calamity which prostrate others, you will find support. You will then be enabled to say, “there is lifting up, or there is support.”

Or, more probably still, it may mean, “in times when others are cast down and afflicted, you will be able to raise them up, or to aid them. You will be able to go to them and say, ‘Be of good cheer. Do not be cast down. There is consolation.’ And you will be able to procure important blessings for them by your counsels and prayers” (see the notes at Job 22:30).

And he shall save the humble person - That is, either, “You will save the humble person” (by a change from the second person to the third, which is not uncommon in Hebrew), or, “you will be able from your own experience to say, ‘He,’ that is, ‘God,’ will save the humble person, or the one that is cast down.”

The margin reads, “him that has low eyes.” The Hebrew is like the margin.

In affliction, the eyes are cast upon the ground; and so, also, casting the eyes to the ground is indicative of dejection, humility, or modesty. It refers here to one who experiences trials; and Eliphaz says that Job would be able to save such a one—that is, to support him in his afflictions and furnish the help necessary to restore him again to comfort.
