Builded an altar there - That he might have a place for God's worship, as well as a place for himself and family to dwell in.

And called upon the name of the Lord - And invoked in the name of Jehovah. See note on Genesis 12:8; See note on Genesis 13:15.

And he builded an altar there,.... At Beersheba, where his father Abraham had planted a grove before, and very probably had built an altar also, though it might not be now standing, Genesis 21:33,

and called upon the name of the Lord; and gave him thanks for all his mercies to him; for the care he had taken of him, and provision he had made for him and his during the time of famine; and for the protection and preservation of him in Gerar; and for his deliverance of him out of the hands of envious, malicious, and unreasonable men; as well as prayed unto him for present and future mercies, for providential care of him and his; and for communications of special grace, and for meetness for eternal glory; all which every good man daily prays to God for:

and pitched his tent there: intending to take up his abode and settle there:

and there Isaac's servants digged a well; in order to find water for the family, and for the flocks and herds; and which was necessary to be done, as they perceived their master designed to fix his habitation here; wells of water being of great moment and consequence in those hot and desert countries, as the above contentions about them abundantly show.

And he builded an {x} altar there, and called upon the name of the LORD, and pitched his tent there: and there Isaac's servants digged a well.

(x) To signify that he would serve no other God, but the God of his father Abraham.

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.
