Ishmael's Unspoken Name and the Well Hagar Could Not See (Genesis 21)

In Hebrew, Ishmael's name never appears in Genesis 21. Verse 11 in the Berean Standard Bible says the matter "concerned his son Ishmael" (Genesis 21:11), but the Hebrew says only his son, and from the feast until his mother finds him a wife from Egypt he is the son of the slave woman or simply the boy. The narrator holds the name back for the whole chapter. Then, at the moment the boy is about to die, God acts it out.

What was Ishmael doing in Genesis 21:9?

Sarah "saw that the son whom Hagar the Egyptian had borne to Abraham was mocking her son" (Genesis 21:9). The verb is metsacheq, from tsachaq (H6711), the same root as Yitschaq (H3327), Isaac. Three verses after Sarah said "God has made me laugh" (Genesis 21:6), she sees the older boy doing the younger boy's name.

In this intensive form the verb has a wide range of meanings. It is Isaac "caressing his wife Rebekah" (Genesis 26:8), Potiphar's wife accusing Joseph of coming "to make sport of us" (Genesis 39:14), and Israel at the golden calf getting up "to indulge in revelry" (Exodus 32:6). So mocking is one fair reading, and playing is another. Paul read it as hostility: "the son born by the flesh persecuted the son born by the Spirit" (Galatians 4:29).

An English reader sees a teenager teasing a toddler. A Hebrew listener heard a question about who gets to be Isaac. Sarah's answer, in the next verse, is legal.

Sarah's demand and the old law

Her verb is garash (H1644), drive out. Genesis has used it twice before. God "drove out the man" from Eden (Genesis 3:24), and Cain cried, "this day You have driven me from the face of the earth" (Genesis 4:14). Both times someone is sent away from the place where God had put them, and both times God provides for the one sent out: He clothed Adam and Eve with garments of skin before they left (Genesis 3:21), and He put a mark on Cain to protect him (Genesis 4:15). By the time Sarah says garash, a Hebrew listener has learned that the people this verb sends away stay in God's sight.

Sarah's demand also had a legal shape that people across the ancient Near East would have recognised. A law code from the city of Isin, issued by King Lipit-Ishtar about four thousand years ago, rules that when a man frees his slave woman and the children she bore him, those children do not divide the estate with the children of his wife. The Code of Hammurabi has a matching rule for sons a father had not acknowledged as his heirs. Freedom with no share was the formal way to settle a slave mother's sons. That is the whole of Sarah's sentence, "never share in the inheritance" (Genesis 21:10), and it is why Abraham is distressed. The law could release Ishmael and leave him with nothing.

God gave him a promise: "I will also make a nation of the slave woman's son" (Genesis 21:13). Abraham sent his son away carrying a promise the law had no power to give.

Why is the boy never named in Genesis 21?

The only human voice the narrator lets us hear in the desert is Hagar's: "she lifted up her voice and wept" (Genesis 21:16). The voice God answers is the boy's: "God heard the voice of the boy" (Genesis 21:17). The son says nothing on the page, and God hears him anyway.

Heard is shama (H8085), and God is Elohim (H430). Put the verb and the short form of God's name together, yishma and El (H410), and you have Yishma'el (H3458), God hears. The boy's name is said in what God does.

It is the third time. In Genesis 16 the name came with its reason, that the LORD had heard Hagar (Genesis 16:11). When Abraham prayed for the boy, God answered, "As for Ishmael, I have heard you" (Genesis 17:20). Now He hears the boy himself. Each time, God's hearing is joined to a promise God had already spoken. The bowshot comes back at the end of the passage, too. The boy his mother left a bowshot away to die grew up to be "a great archer" (Genesis 21:20), a man of the bow, alive because God heard him.

What does it mean that God opened her eyes?

"Then God opened her eyes, and she saw a well of water" (Genesis 21:19). The verb is paqach (H6491), and it is almost always used of opening eyes. It first appears in the garden, where the serpent promised, "your eyes will be opened" (Genesis 3:5), and then "the eyes of both of them were opened, and they knew that they were naked" (Genesis 3:7). There it opened eyes to shame. Here it opens a mother's eyes to water that was already in the ground.

The clearest echo is Elisha's servant, surrounded by an army, when the prophet prays, "O LORD, please open his eyes that he may see" (2 Kings 6:17). The hills were already full of horses and chariots of fire. In both stories God's provision is already in place, and what changes is that a frightened person can see it. The well, be'er (H875), ties back to Hagar's first meeting with God, at the well that took its name from her words, Beer-lahai-roi (Genesis 16:14), the well of the Living One who sees me.

How did Israel first hear Genesis 21:8–21?

Israel heard this story as a people who had been slaves in Egypt and who knew the Wilderness of Paran first-hand. Their journey from Sinai ended there, "until the cloud settled in the Wilderness of Paran" (Numbers 10:12), and the spies went out from there. They knew what an empty water skin meant. Three days out of the sea they had found no water and cried, "What are we to drink?" (Exodus 15:24).

They also knew garash. God had told Moses that Pharaoh "will drive you out completely" (Exodus 11:1), and they left in such a hurry that they "had been driven out of Egypt" with no provisions prepared (Exodus 12:39). Their rescue began when "God heard their groaning, and He remembered His covenant with Abraham" (Exodus 2:24).

So Israel heard its own story told about an Egyptian slave woman: driven out, carrying bread and water, thirsty in the wilderness, heard by God because of what He had promised Abraham. The God who rescued them had done the same for a woman from the people who enslaved them, on the strength of a promise He had made to her.

Three times Genesis sets God's hearing beside this boy, and each time it is tied to something God had already said. In the desert the promise was the one Hagar already had, and the well was already in the ground; God opened her eyes to both. The boy was known by God where he lay, and Hagar came to know God better by seeing that what He had said was still standing.
