Jamieson, Fausset and Brown on Job 22:29

29. Rather, When (thy ways; from Job 22:28) are cast down (for a time), thou shalt (soon again have joyful cause to) say, There is lifting up (prosperity returns back to me) [Maurer].

he--God.

humble--Hebrew, "him that is of low eyes." Eliphaz implies that Job is not so now in his affliction; therefore it continues: with this he contrasts the blessed effect of being humble under it (Jas 4:6; 1Pe 5:5 probably quote this passage). Therefore it is better, I think, to take the first clause as referred to by "God resisteth the proud." When (men) are cast down, thou shalt say (behold the effects of) pride. Eliphaz hereby justifies himself for attributing Job's calamities to his pride. "Giveth grace to the humble," answers to the second clause.
