And he went up from thence to Beer-sheba. Next follows a more abundant consolation, and one affording effectual refreshment to the mind of the holy man. In the tranquil enjoyment of the well, he acknowledges the favor which God had showed him: but forasmuch as one word of God weighs more with the faithful than the accumulated mass of all good things, we cannot doubt that Isaac received this oracle more joyfully than if a thousand rivers of nectar had flowed unto him: and truly Moses designedly commemorates in lofty terms this act of favor, that the Lord encouraged him by his own word, (Genesis 26:24;) whence we may learn, in ascribing proper honor to each of the other gifts of God, still always to give the palm to that proof of his paternal love which he grants us in his word. Food, clothing, health, peace, and other advantages, afford us a taste of the Divine goodness; but when he addresses us familiarly, and expressly declares himself to be our Father, then indeed it is that he thoroughly refreshes us to satiety. Moses does not explain what had been the cause of Isaac's removal to Beer-sheba, the ancient dwelling-place of his fathers. It might be that the Philistines ceased not occasionally to annoy him; and thus the holy man, worn out with their implacable malice, removed to a greater distance. It is indeed probable, taking the circumstance of the time into account, that he was sorrowful and anxious; for as soon as he had arrived at that place, God appeared unto him on the very first night. Here, then, something very opportune is noticed. Moreover, as often as Moses before related that God had appeared unto Abraham, he, at the same time, showed that the holy man was either tormented with grievous cares, or was held in suspense under some apprehension, or was plunged in sadness, or, after many distresses, was nearly borne down by fatigue, so as to render it apparent that the hand of God was seasonably stretched out to him as his necessity required, lest he should sink under the evils which surrounded him. So now, as I explain it, he came to Isaac, for the purpose of restoring him, already wearied and broken down by various miseries.
And he went up from thence to Beersheba. From the place he last, removed unto Beersheba; the famine being over, he returns to the place where he and his rather formerly lived, Genesis 21:33.
Isaac's Journey to Beersheba. - Here, where Abraham had spent a long time (Genesis 21:33.), Jehovah appeared to him during the night and renewed the promises already given; upon which, Isaac built an altar and performed a solemn service. Here his servants also dug a well near to the tents.
