Job 9:30

“If I wash myself with snow water, etc.] As it came from heaven, or flowed from the mountains covered with snow, as Lebanon, (see <241814> Jeremiah 18:14); or was kept in vessels for such use, as being judged the best for such a purpose; so it was used by the ancients f409, as being what whitens the skin, and strengthens the parts by contracting the pores, and hindering perspiration; it signifies, in a figurative sense, that let him take what methods he would to cleanse himself from sin, they were all in vain, his iniquity would be seen, and remain marked before God; and indeed there is nothing that a man can do that will make him pure and clean in the sight of an holy God; this is not to be…”

“snow water--thought to be more cleansing than common water, owing to the whiteness of snow (Psa 51:7; Isa 1:18). never so clean--Better, to answer to the parallelism of the first clause which expresses the cleansing material, "lye:" the Arabs used alkali mixed with oil, as soap (Psa 73:13; Jer 2:22).”

“If I wash myself with snow water - If I should make myself as pure as possible, and should become, in my view, perfectly holy. Snow water, it seems, was regarded as especially pure. The whiteness of snow itself perhaps suggested the idea that the water of melted snow was better than other for purification. Washing the hands formerly was an emblem of cleansing from guilt. Hence Pilate, when he gave up the Savior to death, took water and washed his hands before the multitude, and said that he was innocent of his blood; Matthew 27:24. The expression used here by Job, also is imitated by the Psalmist, to denote his innocence: I will wash mine hands in innocency: So will I compass thine altar, O…”

“If - If I clear myself from all imputations, and fully prove my innocency before men. Job 9:31”

“9:30 wash myself: Job spoke of cleansing himself with the strongest soap to represent ridding himself of all sin (1:5; cp. Ps 26:6; Matt 27:24).”
