“And Abram journeyed, going on still toward the south.”
King James Version (KJV)
12:7 And the Lord appeared to Abram - Probably in a vision, and spoke to him comfortable words; Unto thy seed will I give this land - No place or condition can shut us out from God's gracious visits. Abram is a sojourner, unsettled, among Canaanites, and yet here also he meets with him that lives, and sees him. Enemies may part us and our tents, us and our altars, but not us and our God.
12:8 And there he built an altar unto the Lord who appeared to him, and called on the name of the Lord - Now consider this, As done upon a special occasion when God appeared to him, then and there he built an altar, with an eye to the God that appeared to him: thus he acknowledged with thankfulness God's kindness to him in making him that gracious visit and promise: and thus he testified his confidence in, and dependence upon the word which God had spoken. As his constant practice, whithersoever he removed. As soon as Abram was got to Canaan, though he was but a stranger and sojourner there, yet he set up, and kept up, the worship of God in his family; and wherever he had a tent, God had an altar and that an altar sanctified by prayer.
12:10 And there was a famine in the land - Not only to punish the iniquity of the Canaanites, but to exercise the faith of Abram. Now he was tried whether he could trust the God that brought him to Canaan, to maintain him there, and rejoice in him as the God of his salvation, when the fig - tree did not blossom. And Abram went down into Egypt - See how wisely God provides, that there should be plenty in one place, when there was scarcity in another; that, as members of the great body, we may not say to one another, I have no need of you.
