And it came to pass, that when Isaac was old, and his eyes were dim, so that he could not see, he called Esau his eldest son, and said unto him, My son: and he said unto him, Behold, here am I.

Now Isaac was old, and his eyes were dim, and he could not see: and he called Esau, his elder son, and said to him: My son? And he answered: Here I am.

And it came to pass when Isaac had become old, and his eyes were dim so that he could not see, that he called Esau his elder son, and said to him, My son! And he said to him, Here am I.

And it cometh to pass that Isaac is aged, and his eyes are too dim for seeing, and he calleth Esau his elder son, and saith unto him, 'My son;' and he saith unto him, 'Here am I.'

And it came to pass, that when Isaac was old, and his eyes were dim, so that he could not see, he called Esau his oldest son, and said to him, My son: and he said to him, Behold, here am I.

Now when Isaac was old and his eyes had become clouded so that he was not able to see, he sent for Esau, his first son, and said to him, My son: and he said, Here am I.

Now Isaac was old, and his eyes were cloudy, and so he was not able to see. And he called his elder son Esau, and he said to him, "My son?" And he responded, "Here I am."

Fuit autem quum senuisset Ishac, et caligassent oculi ejus ita ut non videret, vocavit Esau filium suum majorem, et dixit ad eum, Fili mi. Et dixit ad eum, Ecce adsum.

And it came to pass that when Isaac was old. In this chapter Moses prosecutes, in many words, a history which does not appear to be of great utility. It amounts to this; Esau having gone out, at his father's command, to hunt; Jacob, in his brother's clothing, was, by the artifice of his mother, induced to obtain by stealth the blessing due by the right of nature to the firstborn. It seems even like child's play to present to his father a kid instead of venison, to feign himself to be hairy by putting on skins, and, under the name of his brother, to get the blessing by a lie. But in order to learn that Moses does not in vain pause over this narrative as a most serious matter, we must first observe, that when Jacob received the blessing from his father, this token confirmed to him the oracle by which the Lord had preferred him to his brother. For the benediction here spoken of was not a mere prayer but a legitimate sanction, divinely interposed, to make manifest the grace of election. God had promised to the holy fathers that he would be a God to their seed for ever. They, when at the point of death, in order that the succession might be secured to their posterity, put them in possession, as if they would deliver, from hand to hand, the favor which they had received from God. So Abraham, in blessing his son Isaac, constituted him the heir of spiritual life with a solemn rite. With the same design, Isaac now, being worn down with age, imagines himself to be shortly about to depart this life, and wishes to bless his firstborn son, in order that the everlasting covenant of God may remain in his own family. The Patriarchs did not take this upon themselves rashly, or on their own private account, but were public and divinely ordained witnesses. To this point belongs the declaration of the Apostle, "the less is blessed of the better." (Hebrews 7:7.) For even the faithful were accustomed to bless each other by mutual offices of charity; but the Lord enjoined this peculiar service upon the patriarchs, that they should transmit, as a deposit to posterity, the covenant which he had struck with them, and which they kept during the whole course of their life. The same command was afterwards given to the priests, as appears in Numbers 6:24, and other similar places. Therefore Isaac, in blessing his son, sustained another character than that of a father or of a private person, for he was a prophet and an interpreter of God, who constituted his son an heir of the same grace which he had received. Hence appears what I have already said, that Moses, in treating of this matter, is not without reason thus prolix. But let us weigh each of the circumstances of the case in its proper order; of which this is the first, that God transferred the blessing of Esau to Jacob, by a mistake on the part of the father; whose eyes, Moses tells us, were dim. The vision also of Jacob was dull when he blessed his grandchildren Ephraim and Manasseh; yet his want of sight did not prevent him from cautiously placing his hands in a transverse direction. But God suffered Isaac to be deceived, in order to show that it was not by the will of man that Jacob was raised, contrary to the course of nature, to the right and honor of primogeniture.

Isaac was old - It is conjectured, on good grounds, that Isaac was now about one hundred and seventeen years of age, and Jacob about fifty-seven; though the commonly received opinion makes Isaac one hundred and thirty-seven, and Jacob seventy-seven; but see note on Genesis 31:55, etc.
And his eyes were dim - This was probably the effect of that affliction, of what kind we know not, under which Isaac now labored; and from which, as well as from the affliction, he probably recovered, as it is certain he lived forty if not forty-three years after this time, for he lived till the return of Jacob from Padan-aram; Genesis 35:27-29.

And it came to pass, that when Isaac was old,.... He is generally thought to be about one hundred and thirty seven years of age at this time, which was just the age of his brother Ishmael when he died, Genesis 25:16; and might put him in mind of his own death as near at hand; though if he was no older, he lived after this forty three years, for he lived to be one hundred and eighty years old, Genesis 35:28,
and his eyes were dim, so that he could not see; which circumstance is mentioned, not only as a sign of old age, and as common to it, but for the sake of the following history, and as accounting for it, that he should not know Jacob when he blessed him; and this was so ordered in Providence, that by means of it the blessing might be transferred to him, which otherwise in all probability would not have been done, if Isaac had had his sight:
he called Esau his eldest son; who though he was married, and had been married thirty seven years at this time, yet still lived in his father's house, or near him; for as he was born when his father was sixty years of age, and he married when he himself was forty, and his father must be an hundred, so if Isaac was now one hundred and thirty seven, Esau must have been married thirty seven years; and though he had disobliged his father by his marriage, yet he retained a natural affliction for him; nor had he turned him out of doors, nor had he any thoughts of disinheriting him; but on the contrary intended to bestow the blessing on him as the firstborn, for which reason he is here called "his eldest son":
and said unto him, my son; owning the relation, expressing a tender affection for him, and signifying he had something further to say unto him:
and he said unto him, behold, here am I; by which Esau intimated he was ready to hear what his father had to say to him, and was willing to obey him. The Targum of Jonathan says, this was the fourteenth of Nisan, when Isaac called Esau to him.

The promises of the Messiah, and of the land of Canaan, had come down to Isaac. Isaac being now about 135 years of age, and his sons about 75, and not duly considering the Divine word concerning his two sons, that the elder should serve the younger, resolved to put all the honour and power that were in the promise, upon Esau his eldest son. We are very apt to take measures rather from our own reason than from Divine revelation, and thereby often miss our way.

INFIRMITY OF ISAAC. (Genesis. 27:1-27)
when Isaac was old, and his eyes were dim--He was in his hundred thirty-seventh year; and apprehending death to be near, Isaac prepared to make his last will--an act of the gravest importance, especially as it included the conveyance through a prophetic spirit of the patriarchal blessing.

When Isaac had grown old, and his eyes were dim, so that he could no longer see (מראת from seeing, with the neg. מן as in Genesis 16:2, etc.), he wished, in the consciousness of approaching death, to give his blessing to his elder son. Isaac was then in his 137th year, at which age his half-brother Ishmael had died fourteen years before;
(Note: Cf. Lightfoot, opp. 1, p. 19. This correct estimate of Luther's is based upon the following calculation: - When Joseph was introduced to Pharaoh he was thirty years old (Genesis 41:46), and when Jacob went into Egypt, thirty-nine, as the seven years of abundance and two of famine had then passed by (Genesis 45:6). But Jacob was at that time 130 years old (Genesis 47:9). Consequently Joseph was born before Jacob was ninety-one; and as his birth took place in the fourteenth year of Jacob's sojourn in Mesopotamia (cf. Genesis 30:25, and Genesis 29:18, Genesis 29:21, and Genesis 29:27), Jacob's flight to Laban occurred in the seventy-seventh year of his own life, and the 137th of Isaac's.)
and this, with the increasing infirmities of age, may have suggested the thought of death, though he did not die till forty-three years afterwards (Genesis 35:28). Without regard to the words which were spoken by God with reference to the children before their birth, and without taking any notice of Esau's frivolous barter of his birthright and his ungodly connection with Canaanites, Isaac maintained his preference for Esau, and directed him therefore to take his things (כּלים, hunting gear), his quiver and bow, to hunt game and prepare a savoury dish, that he might eat, and his soul might bless him. As his preference for Esau was fostered and strengthened by, if it did not spring from, his liking for game (Genesis 25:28), so now he wished to raise his spirits for imparting the blessing by a dish of venison prepared to his taste. In this the infirmity of his flesh is evident. At the same time, it was not merely because of his partiality for Esau, but unquestionably on account of the natural rights of the first-born, that he wished to impart the blessing to him, just as the desire to do this before his death arose from the consciousness of his patriarchal call.

Here is Isaac's design to declare Esau his heir. The promise of the Messiah and the land of Canaan was a great trust first committed to Abraham, inclusive and typical of spiritual and eternal blessings; this by divine direction he transmitted to Isaac. Isaac being now old, and either not knowing, or not duly considering the divine oracle concerning his two sons, that the elder should serve the younger, resolves to entail all the honour and power that was wrapt up in the promise upon Esau, his eldest son. He called Esau - Tho' Esau, had greatly grieved his parents by his marriage, yet they had not expelled him, but it seems were pretty well reconciled to him.
