Charles Ellicott Commentary Genesis 12:4

"So Abram went, as Jehovah had spoken unto him; and Lot went with him: and Abram was seventy and five years old when he departed out of Haran." — Genesis 12:4 (ASV)

Abram ... departed out of Haran. —The command given him in Ur may have been repeated in Haran; but more probably Abram had remained there only on account of Terah. At his death (see note on Genesis 11:26) he resumed his migration northward.
