Genesis 13:1-4

XIII.
ABRAM’S RETURN FROM EGYPT AND HIS SEPARATION FROM LOT.

(1-4) He went on his journeys. — Or, according to his stations, which the Vulgate very reasonably translates, “by the same route by which he had come.” This route was first into the south, the Negeb, which is virtually a proper name, and thence to the spot between Beth-el and Ai mentioned in Genesis 12:8.

At the first does not mean that this was the first altar erected by Abram, but that he built it on his first arrival there. His first altar was at Shechem. As regards his wealth, while his cattle had been greatly increased in Egypt, he had probably brought the silver and gold with him from Mesopotamia. Gold, however, was plentiful at that time in Egypt, but silver rare.
