31. Thou shalt not give me anything. The antithesis between this and the preceding clause is to be noticed. For Jacob does not demand for himself certain and definite wages; but he treats with Laban, on this condition, that he shall receive whatever offspring may be brought forth by the sheep and goats of a pure and uniform color, which shall prove to be party-coloured and spotted. There is indeed some obscurity in the words. For, at first, Jacob seems to require for himself the spotted sheep as a present reward. But from the thirty-third verse (Genesis 30:33) another sense may be gathered: namely, that Jacob would suffer whatever was variegated in the flock to be separated and delivered to the sons of Laban to be fed; but that he himself would retain the unspotted sheep and goats. And certainly it would be absurd that Jacob should now claim part of the flock for himself, when he had just confessed, that hitherto he had made no gain. Moreover, the gain thus acquired would have been more than was just; and there was no hope that this could be obtained from Laban. A question however arises, by what hope, or by what counsel bad Jacob been induced to propose this condition? A little afterwards, Moses will relate that he had used cunning, in order that party-coloured and spotted lambs might be brought forth by the pure flock; but in the following chapter he more fully declares that Jacob had been divinely instructed thus to act (Genesis 31:1.) Therefore, although it was improbable in itself that this agreement should prove useful to the holy man, he yet obeys the celestial oracle, and wishes to be enriched in no other manner than according to the will of God. But Laban was dealt with according to his own disposition; for he eagerly caught at what seemed advantageous to himself, but God disappointed his shameful cupidity.
