Beth-el. In need of fresh pastureland, Abram moved from the vicinity of Shechem to the east of Bethel, 20 mi. farther to the south. Abram pitched his tent on one of the hilltops between the cities of Bethel and Ai. The city is here referred to by the name it bore in later times. It was still called Luz in Abram’s time (see ch. 28:19). This Canaanite city, now called Beitin, lies about 10 mi. north of Jerusalem. It played an important role in Jacob’s life (ch. 28:19; 35:1), and was one of the first cities of Canaan conquered by Joshua. During the period of the divided kingdom, one of the two idolatrous cult places of Israel was situated there (1 Kings 12:28, 29). Scholars have identified the present Et-Tell with Ai, because of the similarity of names, Ai being the Hebrew name for “ruin,” whereas Tell is the Arabic name for a ruined site. This identification is, however, questionable.
He builded an altar. Abram erected an altar, wherever he pitched his tent (see Gen. 12:7; 13:18), and conducted public worship for the members of his household and for pagans living nearby. Although the service was presumably simple, consisting essentially in prayer, the offering of a sacrificial animal, and doubtless an evangelistic appeal, the great number of retainers whom Abram had led to a knowledge of Jehovah must have made these occasions impressive (see ch. 14:14; 18:19). Many keep their faith secret, afraid to confess it, but not Abram. Wherever he went he confessed the One whom he trusted and obeyed. His altars dotting the Palestinian countryside became memorials to the one true God. The Canaanites, whose iniquity was not yet full (ch. 15:16), were thus made acquainted with the Creator of the universe, and by Abram’s precept and example were called upon to discard their idols and worship Him. The world’s first foreign missionary, Abram journeyed tirelessly through Palestine and preached God wherever he pitched his tent. Isaac and Jacob were also called of God to spend their lives in this land. Although these men were not always shining examples of truth, the Canaanites could not but see the difference between their own way of life and that of the Hebrews. When the time of their judgment should come they could not deny that God had provided them every opportunity to learn of Him.
