4. Unstable as water. He shows that the honor which had not a good conscience for its keeper, was not firm but evanescent; and thus he rejects Reuben from the primogeniture. He declares the cause, lest Reuben should complain that he was punished when innocent: for it was also of great consequence, in this affair, that he should be convinced of his fault, lest his punishment should not be attended with profit. We now see Jacob, having laid carnal affection aside, executing the office of a prophet with vigor and magnanimity. For this judgment is not to be ascribed to anger, as if the father desired to take private vengeance of his son: but it proceeded from the Spirit of God; because Jacob kept fully in mind the burden imposed upon him. The word עלח ( alach) the close of the sentence signifies to depart, or to be blown away like the ascending smoke, which is dispersed. (196) Therefore the sense is, that the excellency of Reuben, from the time that he had defiled his father’s bed, had flowed away and become extinct. For to expound the expression concerning the bed, to mean that it ceased to be Jacob’s conjugal bed, because Bilhah had been divorced, is too frigid.
(196) The literal translation of Calvin’s version is, “Thy velocity was like that of water, thou shalt not excel: because thou wentest up into thy father’s couch, then thou pollutedst my bed, he has vanished.” This gives the patriarch’s expression a different turn from that supposed by our translators; who understand the last word in the sentence to be a repetition of what had been said before, only putting it in the third person, as expressive of indignation; as if he had turned round from Reuben to his other children and said — “Yes, I declare he went up into my bed!” Another view is given in the margin of our Bible, “My couch is gone;” which means that, by this defilement, the marriage bond was broken. To this version Calvin objects at the close of the paragraph. But both these constructions seem forced. Calvin’s appears the most natural. He represents Reuben as having lost all, by his criminal conduct. Honour, excellence, priority, virtue, and consequently character and influence, had all gone up as the dew from the face of the earth, and had vanished away. — Ed.
