Job 42:5

I have heard of thee - I have now such a discovery of thee as I have never had before. I have only heard of thee by tradition, or from imperfect information; now the eye of my mind clearly perceives thee, and in seeing thee, I see myself; for the light that discovers thy glory and excellence, discovers my meanness and vileness.

42:5 now I have seen you: Up to this point, Job had not seen God (see 23:8); now, like Isaiah, he had been in God’s presence and was overwhelmed by God’s holiness (Isa 6:1).

Wherefore I abhor myself,.... Or all my words, as Aben Ezra; all the indecent expressions he had uttered concerning God; he could not bear to think of them; he loathed them, and himself on account of them: sin is abominable in its own nature, and makes men so; it is loathsome to God, and so it is to all good men when they see it in its proper light; am especially when they have a view of the purity and holiness of God, to which that is so very contrary, and also of his grace and goodness in the forgiveness of it; see Isa 6:3, Eze 16:63; and repent in dust and ashes; which was an external ceremony used by mournful and penitent persons; see Job 2:8; and is expressive of the truth and sincerity of repentance; and never do any more truly mourn for sin and repent of it, are more ashamed of it, or have a more godly sorrow for it, or more ingenuously confess it, and heartily forsake it, than those who with an eye of faith behold God in Christ as a sin forgiving God; or behold their sins through the glass of pardoning grace and mercy; see Zac 12:10.
