Verse 24. - And the Lord appeared unto him the same night (i.e. the night of his arrival at Beersheba), and said (in a dream or vision), I (the pronoun is emphatic) am the God (the Elohim) of Abraham thy father (the language is expressive not alone of the covenant relationship which subsisted between Jehovah and the patriarch while the latter lived, but also of the present continuance of that relationship, since Abraham, though dead, had not ceased to he): fear not (cf. Genesis 15:1, in which the same encouraging admonition is addressed to Abraham after his battle with the kings), for I am with thee, and will bless thee, and multiply thy seed - a repetition of promises already given to himself (vide vers. 3, 4) - for my servant Abraham's sake - a reason declaring God's gracious covenant, and not personal merit, to be the true source of blessing for Isaac.

26:18-25 Isaac met with much opposition in digging wells. Two were called Contention and Hatred. See the nature of worldly things; they make quarrels, and are occasions of strife; and what is often the lot of the most quiet and peaceable; those who avoid striving, yet cannot avoid being striven with. And what a mercy it is to have plenty of water; to have it without striving for it! The more common this mercy is, the more reason to be thankful for it. At length Isaac digged a well, for which they strove not. Those that study to be quiet, seldom fail of being so. When men are false and unkind, still God is faithful and gracious; and his time to show himself so is, when we are most disappointed by men. The same night that Isaac came weary and uneasy to Beer-sheba, God brought comforts to his soul. Those may remove with comfort who are sure of God's presence.And the Lord appeared to him in the same night,.... The first night he came to Beersheba, in a dream or vision, in which the Lord was represented as speaking to him:

and said, I am the God of Abraham thy father; though he was dead, he remembered the covenant he made with him, and the promises he made unto him: and besides, though Abraham was dead as to his body, yet alive in his soul; for God is not the God of the dead, but of the living, Matthew 22:32,

fear not; any future famine, nor want of any good things, nor any enemies, the Philistines his neighbours, who had driven him from their country, and had harassed him from place to place:

for I am with thee, and will bless thee; and if God is with his people, they have nothing to fear from men; and if he blesses them, they are blessed, and no curse can light upon them:

and multiply thy seed, for my servant Abraham's sake; who was a faithful, diligent, servant of his; whose service was, not forgotten by him, but would be rewarded in a way of grace, though not of debt.
