Carl Friedrich Keil and Franz Delitzsch Old Testament Commentary

6 The rectitude of the upright saveth them, And in their own covetousness are the faithless taken. The integrity of those who go straight forward and straight through, without permitting themselves to turn aside on crooked ways, delivers them from the snares which are laid for them, the dangers they encounter; while, on the contrary, the faithless, though they mask their intentions ever so cunningly, are ensnared in their passionate covetousness: the mask is removed, they are convicted, and are caught and lost. Regarding הוּה, abyss, overthrow, also stumbling against anything = covetousness, vid., at Pro 10:3, and under Psa 5:10. The form of the expression 6b follows the scheme, "in the image of God created He man," Gen 9:6. The subject is to be taken from the genitive, as is marked by the accentuation, for it gives Mugrash to the וּבהוּת, as if it were the principal form, for וּבהוּה.
