Job 24:18

He is light, &c. That is, the adulterer, that he may not be perceived and discovered, steps as nimbly and as light as if her were walking upon the waters. Or the sense is: he is as light, that is, as swift and nimble as the running waters. --- By the way of the vineyards. That is, by the way where he may meet with fruit and blessings. (Challoner) --- The wicked are always inconstant. (Calmet) (Isaias lvii. 29.) --- He deserves no temporal nor eternal happiness. If he were deprived of the former, he might perhaps endeavour to escape the torments of hell. (Haydock)
