They abhor me, they flee far from me, and spare not to spit in my face.

Wesley's Notes

30:10 Spit - Not literally, for they kept far from him, but figuratively, they use all manner of reproachful expressions, even to my face. Herein, also we see a type of Christ, who was thus made a reproach of men, and despised of the people.

Jamieson-Fausset-Brown Bible Commentary

10. in my face-rather, refrain not to spit in deliberate contempt before my face. To spit at all in presence of another is thought in the East insulting, much more so when done to mark "abhorrence." Compare the further insult to Jesus Christ (Isa 50:6; Mt 26:67).

Matthew Henry's Concise Commentary

30:1-14 Job contrasts his present condition with his former honour and authority. What little cause have men to be ambitious or proud of that which may be so easily lost, and what little confidence is to be put in it! We should not be cast down if we are despised, reviled, and hated by wicked men. We should look to Jesus, who endured the contradiction of sinners.
