GenesisChapter 18

+ Secondary text Original text ← Previous Next →Contribute

The LORD appeared to Abraham by the oaks of Mamre as he sat at the entrance of his tent in the heat of the day.

He looked up and saw three men standing nearby. When he saw them, he ran from the tent entrance to meet them and bowed to the ground.

"My lord," he said, "if I have found favor in your eyes, do not pass by your servant.

Let a little water be brought, and wash your feet, and rest under the tree.

Let me bring a piece of bread to refresh you, and then go on your way—since you have come by your servant." "Very well," they said, "do as you have said."

Abraham hurried into the tent to Sarah. "Quick," he said, "three measures of the finest flour! Knead it and bake bread." [footnote: About twenty liters.]

Then he ran to the herd, took a choice, tender calf, and gave it to his servant, who hurried to prepare it.

He took curds and milk and the calf that had been prepared, and set it all before them, and he stood by them under the tree while they ate.

They asked him, "Where is Sarah your wife?" "There, in the tent," he said.

Then he said, "I will surely return to you about this time next year, and Sarah your wife will have a son." Now Sarah was listening at the entrance of the tent, behind him.

Abraham and Sarah were old, well along in years, and Sarah was long past childbearing.

So Sarah laughed to herself and thought, "Now that I am worn out, am I to have pleasure? And my husband is old."

But the LORD said to Abraham, "Why did Sarah laugh and say, 'Can I really bear a child, now that I am old?'

Is anything too hard for the LORD? At the appointed time I will return to you, about this time next year, and Sarah will have a son."

Sarah denied it: "I did not laugh"—for she was afraid. But he said, "Yes, you did laugh."

Then the men got up to leave and looked down toward Sodom, and Abraham walked along with them to see them on their way.

And the LORD said, "Shall I hide from Abraham what I am about to do?

Abraham will surely become a great and mighty nation, and through him all the nations of the earth will be blessed.

For I have chosen him, so that he will direct his children and his household after him to keep the way of the LORD by doing what is right and just, so that the LORD may bring about for Abraham what he has promised him."

Then the LORD said, "The outcry against Sodom and Gomorrah is great, and their sin is very grave.

I will go down now and see whether they have acted as badly as the outcry that has reached me. If not, I will know.

The men turned from there and went toward Sodom, but Abraham remained standing before the LORD.

Then Abraham came near and said, "Will you really sweep away the righteous with the wicked?

Suppose there are fifty righteous people in the city. Will you really sweep it away and not spare the place for the sake of the fifty righteous who are in it?

Far be it from you to do such a thing—to kill the righteous with the wicked, treating the righteous and the wicked alike! Far be it from you! Will not the Judge of all the earth do what is just?"

The LORD said, "If I find fifty righteous people in the city of Sodom, I will spare the whole place for their sake."

Abraham answered, "Now that I have ventured to speak to the Lord, though I am but dust and ashes—

suppose the fifty righteous are five short. Will you destroy the whole city because of five?" "If I find forty-five there," he said, "I will not destroy it."

Abraham spoke to him again: "What if only forty are found there?" He said, "For the sake of the forty, I will not do it."

Then he said, "May the Lord not be angry, but let me speak. Suppose only thirty are found there?" He answered, "If I find thirty there, I will not do it."

He said, "Now that I have ventured to speak to the Lord, suppose only twenty are found there?" He said, "For the sake of the twenty, I will not destroy it."

Then he said, "May the Lord not be angry, but let me speak just once more. Suppose only ten are found there?" He answered, "For the sake of the ten, I will not destroy it."

When the LORD had finished speaking with Abraham, he went on his way, and Abraham returned home.

Historical context

Historical and Cultural Context for Genesis 18

Places

The oaks of Mamre (אֵלֹנֵי מַמְרֵא) are located near Hebron, about 30 kilometers south of Jerusalem. The site was already established as Abraham’s base in Genesis 13:18, and the terebinth trees provided valuable shade during the hot season—explaining why Abraham sat at the tent entrance "in the heat of the day" (v. 1).

Sodom is mentioned in this chapter as the target of God’s judgment. The city was likely situated in the southern part of the Dead Sea plain, an area that geological studies show has been subject to seismic activity and asphalt deposits.

Events and Customs

Abraham’s hospitality customs reflect fundamental values in the ancient Near East. Offering water for foot washing, rest under trees, and food for travelers was not merely politeness but a sacred duty. Similar hospitality protocols are documented in Ugaritic and Mesopotamian texts from the same period. To refuse hospitality was a serious social offense, which later becomes central to the judgment against Sodom.

The meal Abraham prepared was extraordinarily lavish: three seahs (about 22 liters) of fine flour for bread, a whole calf, as well as curds and milk. This far exceeded normal hospitality and signaled that Abraham recognized his guests’ special status. The fact that he himself stood and served them while they ate was a sign of deep respect—the host’s role as servant underscored the honor due to the guests.

Key Terms

"Adonai" (אֲדֹנָי) in verse 3 is textually interesting. The Masoretic Text marks this term as holy, indicating that Abraham was addressing the Lord Himself, not merely being polite to one of the men. The shifting references between the three men and the Lord (YHWH) throughout the chapter have given rise to various interpretations—both as a theophany (divine manifestation) and as an angelic visitation.

"Dust and ashes" (עָפָר וָאֵפֶר) in verse 27 is Abraham’s self-description when he negotiates with God. The expression combines two words for what is most worthless and perishable, representing extreme humility. This rhetoric—humbling oneself before making a bold request—is well known from Mesopotamian prayer texts and diplomatic correspondence of the period.

"Righteousness and justice" (צְדָקָה וּמִשְׁפָּט) in verse 19 is a word pair that becomes central in prophetic literature. Here it is used for the first time in the Bible to describe the way of life Abraham is to pass on to his descendants, establishing a connection between ethical conduct and the covenant relationship with God.
