Shared ground
Genesis 33:18–20 presents a short sequence that moves Jacob from travel to a settled foothold in Canaan. The text explicitly reports (1) a safe arrival at Shechem, (2) camping near the city, (3) a paid purchase of the exact plot where his tent stood, and (4) an altar built on that purchased site. Taken together, these actions show Jacob establishing a recognized place for his household and a defined location for worship.
The story also ties place and identity together. By naming the altar “El-Elohe-Israel,” Jacob publicly links the God he worships (“El”) with “Israel,” the name Jacob bears. That is an inference from the naming act, but it is grounded in the text’s emphasis on the altar name and its location.
Where interpretation differs
Two details invite more than one reasonable reading.
First, “came in peace” can be taken mainly as “arrived safely/whole,” or as “arrived on good terms” (peaceful relations) with the people of the area. The passage clearly stresses a non-disastrous arrival, but it does not spell out the social side.
Second, “encamped before the city” can mean outside the city walls, or more generally “near the city.” Either way, Jacob positions his household close enough for contact and commerce, but not necessarily inside the town.
Third, the meaning of the altar name can be read with slightly different emphasis: either “God, the God of Israel” (a statement about who God is for Israel) or “God of Israel” (a statement about whose God Jacob/Israel worships). The Hebrew phrasing allows both senses to be heard.
Why the disagreement exists
The differences come from brief phrases that can carry more than one shade of meaning (“in peace,” “before the city”), and from an altar name that compresses meaning into a few words without explanation. The text gives the actions clearly, but it leaves some relational and linguistic nuance implicit.
What this passage clearly contributes
This passage contributes a picture of Jacob’s return becoming concrete: he is not only passing through but establishing a lawful claim to land by purchase, and marking that land as a worship site by building an altar. It also sets up the next chapter by placing Jacob’s household near Shechem and in contact with the ruling family named here (Hamor’s household; see Genesis 34:1).
