Genesis 26:24

Genesis 26 opens with Isaac living in Gerar because of a famine (Genesis 26:1–22). There the Philistines stopped up the wells his father Abraham had dug, and when Isaac’s servants dug new ones, the Philistines disputed those too. Isaac moved on from Esek to Sitnah and then to Rehoboth (Genesis 26:15–22), and from there he went up to Beersheba (Genesis 26:23). For people who lived by their flocks, water meant survival, and whoever held the wells held a claim to the land and its wealth. Stopping up Isaac’s wells was an act of hostility meant to push him out.

The LORD appears to him “the same night”. God answers a weary and unsettled man at the very moment he needs it, with a direct and personal word. This is a theophany, an appearance of God himself to one of his people, and it confirms in Isaac’s own hearing everything he has been promised.

Beersheba already had a history with God’s people. Abraham had made a covenant there with Abimelech (Genesis 21:22–34), and in later years it became a well-known boundary marking the south of Israel’s land.

The LORD speaks first of who he is. The name used here, Yᵉhôvâh, is God’s own personal name, the name of the eternal God who is faithful to his promises and keeps covenant with his people. When he calls himself “the God of Abraham thy father”, he brings into this night all his dealings with Abraham: the call, the promises and the faithfulness Isaac had grown up hearing about (Genesis 12:1–3). From Genesis 12 onward God has guided the patriarchs by speaking to them, and he now speaks to Isaac.

The covenant God made with Abraham passes to Isaac, and this word confirms that he is its rightful heir. Isaac hears from God’s own mouth that his father’s God is his God too.

Isaac had reason to be afraid. He had been driven from well to well by people stronger than he was, and he was still looking for a settled place. To that fear God speaks a command with its reason attached. The verb yârêʼ means to fear, and it can also mean to revere, in the way God’s people fear him with reverence. “Fear not” tells Isaac to let go of his dread and trust God, and the reason is God’s own presence: “for I am with thee”. The God who stands with Isaac is greater than anything that threatens him.

This pairing of “fear not” with the promise of God’s presence runs through Scripture. Through Isaiah God tells his servant Israel, “Fear thou not; for I am with thee” (Isaiah 41:10), and the letter to the Hebrews gives believers the same assurance: “for he hath said, I will never leave thee, nor forsake thee” (Hebrews 13:5). Courage in Scripture rests on who is with us.

God then repeats two parts of the promise first given to Abraham: “I will bless thee, and multiply thy seed.” The verb bârak, to bless, is tied to kneeling, and Scripture uses it both of people blessing God in worship and of God blessing people with good. When God blesses Isaac, he gives him his favor, prosperity and well-being of body and soul. The promise of seed is a promise of many descendants, the people of the covenant and the line through which the Messiah would one day come.

“For my servant Abraham’s sake” gives the reason. God blesses Isaac because of the promises he made to Abraham, and he keeps his word. The blessing rests on God’s faithfulness and his free grace, so Isaac receives it as an heir receives an inheritance. God calls Abraham “my servant”, a title of honor for the man who trusted him and obeyed. What God has promised, he goes on giving from one generation to the next.

Isaac’s first recorded act at Beersheba is to build an altar. The word mizbêach means an altar, a structure for burning sacrifices. The same word names the heathen altars Israel was later told to destroy as well as the LORD’s own altar, so what made Isaac’s altar holy was the God he built it to. An altar was usually raised of earth or unhewn stones, and it was the place to offer sacrifice, to pray, and to mark where God had met someone. By building one, Isaac dedicates the spot to the LORD and gives thanks for the promise he has just heard.

He is doing what his father did. When Abraham came into the land, he built altars to the LORD at Shechem and near Bethel, and there he “called upon the name of the LORD” (Genesis 12:7–8). The same faith passes from father to son, and the pattern of worship joined to daily life runs on from Abraham’s journey to Jacob’s return to Bethel (Genesis 35).

Next Isaac “pitched his tent there”. The patriarchs lived in tents, so this shows Isaac’s intention to stay at Beersheba and make a home there, and it also marks him as a sojourner on the earth. Hebrews says of Abraham, “By faith he sojourned in the land of promise, as in a strange country, dwelling in tabernacles with Isaac and Jacob, the heirs with him of the same promise: For he looked for a city which hath foundations, whose builder and maker is God” (Hebrews 11:9–10). Isaac set up his tent beside his altar, and so his home was centered on the God he worshipped.

Last, “there Isaac’s servants digged a well.” The word bᵉʼêr means a pit or a well, and it comes from a root meaning to dig. In the dry Negev a well was what made it possible to stay, with water for the household and the flocks. After all the quarrels over wells earlier in the chapter, Isaac’s servants dig here, in the place where God has just promised to bless him, and this time the digging goes ahead in peace. The well is God’s practical provision for Isaac, and his blessing reaches daily needs as well as the soul. The name Beer-sheba means “well of the oath” or “well of seven”, and this well came to be tied to that name.

The word “there” comes three times in the verse: an altar there, a tent there, and there a well. Beersheba becomes a place of worship and a place to live, a place of rest and provision after a time of wandering and conflict.

The promise to multiply Isaac’s seed reaches its fullest meaning in Jesus Christ. Paul writes, “Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ” (Galatians 3:16), and “if ye be Christ’s, then are ye Abraham’s seed, and heirs according to the promise” (Galatians 3:29). Christ is the seed through whom all the families of the earth are blessed, as God first told Abraham (Genesis 12:3). God’s faithfulness to Abraham, which went on blessing Isaac despite Isaac’s own flaws, looks ahead to his sending of Christ to bring salvation, reconciliation and adoption into God’s family to all who believe (Ephesians 1:3–6). Christ is the LORD’s righteous servant (Isaiah 53:11), in whom every covenant promise comes to its full fruit.

Isaac’s altar and well point to Christ as well. An altar was a place of sacrifice and communion, and Christ is the perfect sacrifice, the Lamb of God who takes away the sin of the world, through whom we call on the name of the LORD and draw near to God. Hebrews says, “We have an altar”, and calls believers to offer the sacrifice of praise to God through him (Hebrews 13:10–16). Christ is also the living water. At Jacob’s well he told the Samaritan woman that the water he gives becomes in a person “a well of water springing up into everlasting life” (John 4:10–14). In him dwells all the fulness of the Godhead bodily, and we are complete in him (Colossians 2:9–10), so our worship, our homes and our daily provision all find their center in him.

The God of Abraham and Isaac is the same faithful God who watches over us, and through Christ his covenant promises are ours. The word Isaac heard, “fear not: for I am with thee”, rests for us on the same ground, God’s presence and his unchanging word. Our answer can be Isaac’s answer, reverent trust shown in worship. We can build the altar first, making our homes, our work and our daily needs places where God is honored and sought, and we can trust him to provide for the body as well as the soul, as he gave Isaac a well in the place where he worshipped.
