3. And he went on his journeys. In these words Moses teaches us, that Abram did not rest till he had returned to Bethel. For although he pitched his tent in many places, yet he nowhere so fixed his foot, as to make it his permanent abode. He does not speak of the south in reference to Egypt; he merely means that he had come into the southern part of Judea; and that, therefore, he had, by a long and troublesome journey, arrived at the place where he had determined to remain. Moses next subjoins, that an altar had before been there erected by him and that he then also began anew to call upon the name of the Lord: whereby we may learn, that the holy man was always like himself in worshipping God, and giving evidence of his piety. The explanation given by some, that the inhabitants of the place had been brought to the pure worship of God, is neither probable, nor to be deduced from the words of Moses. And we have stated elsewhere what is the force of the expression, ‘To invoke in the name,’ or, ‘To call upon the name of the Lord;’ namely, to profess the true and pure worship of God. For Abram invoked God, not twelve times only, during the whole course of his life; but whenever he publicly celebrated him, and by a solemn rite, made it manifest that he had nothing in common with the superstitions of the heathen, then he is also said to have called upon God. Therefore, although he always worshipped God, and exercised himself in daily prayers; yet, because he did not daily testify his piety by outward profession before men, this virtue is here especially commended by Moses. It was therefore proper that invocation should be conjoined with the altar; because by the sacrifices offered, he plainly testified what God he worshipped in order that the Canaanites might know that he was not addicted to their common idolatries.
