Loved ones, the life of faith is not entirely made up of dramatic mountaintop experiences or agonizing crises. Much of our walk with God happens in the ordinary, dusty realities of everyday life—navigating relationships with unbelieving neighbors, resolving property disputes, and finding a place to quietly put down roots.
Following the intense emotional highs and lows of Isaac’s birth and Ishmael’s banishment, Genesis 21 concludes with a stabilizing scene of peace. Abraham is living as a sojourner in Philistine territory. Here, we see a beautiful picture of what it looks like for a believer to live a quiet, peaceable, and distinctly holy life in the midst of a watching world. The chapter closes with Abraham claiming a small piece of the Promised Land, planting a slow-growing tree, and lifting his voice to worship God under a brand-new name.
Genesis 21:22-34 records Abimelech’s recognition of God’s favor upon Abraham, the resolution of a dispute over a well at Beersheba, and Abraham’s worship of the LORD as El Olam, the Everlasting God.
Verses 22–24
22 At that time Abimelech and Phicol the commander of his army said to Abraham, “God is with you in all that you do. 23Now therefore swear to me here by God that you will not deal falsely with me or with my descendants or with my posterity, but as I have dealt kindly with you, so you will deal with me and with the land where you have sojourned.” 24And Abraham said, “I will swear.”
The Witness of the World
You may remember King Abimelech from Genesis 20. Just a few years earlier, Abraham had cowardly lied to this king, bringing a curse upon the royal household. It was a humiliating moment where the pagan king possessed more integrity than the prophet of God.
But God is the great restorer of our witness. Over the ensuing years, Abimelech has watched Abraham. He has seen the miraculous birth of Isaac. He has witnessed Abraham’s growing wealth and peaceful demeanor. Now, Abimelech approaches Abraham, flanked by the commander of his army, Phicol, and makes a stunning admission: “God is with you in all that you do.” What a profound testimony! Abimelech doesn’t just see a wealthy herdsman; he sees the undeniable, active presence of the living God in Abraham’s everyday life. Because he recognizes this divine favor, the king essentially asks for a non-aggression treaty. He wants to be on the winning side of God’s blessing. Abraham, acting as an ambassador of peace, readily agrees.
Verses 25–32
25 When Abraham reproved Abimelech about a well of water that Abimelech’s servants had seized, 26 Abimelech said, “I do not know who has done this thing; you did not tell me, and I have not heard of it until today.” 27 So Abraham took sheep and oxen and gave them to Abimelech, and the two men made a covenant. 28 Abraham set seven ewe lambs of the flock apart. 29 And Abimelech said to Abraham, “What is the meaning of these seven ewe lambs that you have set apart?” 30 He said, “These seven ewe lambs you will take from my hand, that this may be a witness for me that I dug this well.” 31Therefore that place was called Beersheba, because there both of them swore an oath. 32 So they made a covenant at Beersheba. Then Abimelech and Phicol the commander of his army rose up and returned to the land of the Philistines.
The Well of the Oath
Before finalizing the treaty, Abraham brings up a point of conflict. In the arid landscape of the ancient Near East, water was more valuable than gold. A well was literally the difference between life and death for a nomadic herdsman. Abimelech’s servants had violently seized a well that Abraham had painstakingly dug.
Notice how Abraham handles this. He does not go to war; he does not seek revenge. He directly, respectfully, and firmly reproves the king. Abimelech pleads ignorance, and the two men move to make it right.
To formalize the covenant, Abraham brings sheep and oxen. But he does something unusual: he sets apart seven ewe lambs. When Abimelech asks about them, Abraham explains that these lambs are a legal receipt—a public, tangible witness that he is the rightful owner of the well.
Because of this sworn agreement and the seven lambs, the place is named Beersheba. In Hebrew, the word sheba sounds like both the word for “seven” and the word for “oath.” Beersheba means “Well of Seven” or “Well of the Oath.” This well would become one of the most famous and sacred landmarks in Israel’s history, a border town marking the southern limit of the Promised Land (“from Dan to Beersheba”).
Verses 33–34
33 Abraham planted a tamarisk tree in Beersheba and called there on the name of the Lord, the Everlasting God. 34 And Abraham sojourned many days in the land of the Philistines.
The Everlasting God
Having secured his right to the water, Abraham does something deeply symbolic: he plants a tamarisk tree. Why is this significant? A tamarisk tree is an evergreen that grows very slowly. It takes decades to reach its full height and provide its deep, cooling shade. A nomad who is just passing through does not plant a tamarisk tree. You only plant a tamarisk if you believe your grandchildren are going to sit under it.
By planting this tree, Abraham is acting in faith. He currently owns nothing in Canaan but a single well, but he knows God’s promise. He is putting down roots. He is claiming the land for future generations.
Under the shade of this newly planted sapling, Abraham calls on the name of the Lord, using a new and magnificent title: El Olam—”The Everlasting God,” or “The God of Eternity.”
Why this name? Abraham had just made a treaty with an earthly king. Earthly kings die. Treaties fade. Wells eventually dry up. But Abraham is anchoring his faith not in the shifting sands of human alliances, but in the eternal, unchanging, everlasting nature of God. From generation to generation, El Olam remains the same.
Conclusion
Abraham models for us the posture of a mature believer in a fallen world. We are called to live peaceably with all men (Romans 12:18). We should strive to live with such integrity, grace, and honesty that even our unbelieving neighbors are forced to say, “God is with you in all that you do.”
Yet, as we dig our wells and negotiate our lives in this world, our ultimate hope can never rest here. Treaties are broken, economies crash, and the things of this earth pass away. Like Abraham, we must look past our temporary circumstances and worship El Olam, the Everlasting God.
Thousands of years after Abraham dug this well, a weary traveler would sit beside another well in Samaria and tell a woman, “Whoever drinks of the water that I will give him will never be thirsty again” (John 4:14). Jesus Christ is the Everlasting God wrapped in human flesh. He is the source of living water that never runs dry. Because He is eternal, the salvation and peace He offers are eternal as well.
