35:7 built an altar. Jacob finally fulfilled his vow to the Lord (28:20–22). By such altar building, the patriarchal family acknowledged the covenant promises and consecrated the Promised Land. Regular worship was crucial if they were to maintain their religious separation from the surrounding Canaanites (ch. 34; Num. 25:1–3 and notes). See 12:7 and note; 13:18; 22:9; 33:20.
