Abram obeys the call. He had set out from Ur under the revered guardianship of his aged father, Terah, with other companions, "as the Lord had spoken unto him." Lot is now mentioned as his companion. Terah's death has been already recorded. Sarai is with him, of course, and therefore it is unnecessary to repeat the fact. But Lot is associated with him as an incidental companion for some time longer. The age of Abram at the second stage of his journey is now mentioned. This enables us to determine, as, we have seen, that he departed from Ur five years before.

And Abram was seventy and five years old - As Abram was now seventy-five years old, and his father Terah had just died, at the age of two hundred and five, consequently Terah must have been one hundred and thirty when Abram was born; and the seventieth year of his age mentioned Genesis 11:26, was the period at which Haran, not Abram, was born. See on Genesis 11 (note).

So Abram departed, as the Lord had spoken unto him,.... Or, "when the Lord had spoken to him", as Cocceius renders the words; when he had called him a second time, even when in Haran, immediately after the death of his father Terah; as soon as ever the words were spoken to him before recorded, he immediately prepared and got all things ready for his journey, and departed from Haran, as he had done before from Ur of the Chaldees:

and Lot went with him; of his own accord, and he only, besides his wife Sarai and his servants, for Terah was dead, and Nahor and his family stayed behind.

And Abram was seventy five years old when he departed out of Haran; by which it appears, as has been observed, that he was not Terah's eldest son, born when he was seventy years of age, Genesis 11:26 for then he must have been at this time, one hundred and thirty five years old, since his father, who was just now dead, lived to be two hundred and five years old, Genesis 11:32 so that Abram must be born in the one hundred and thirtieth year of Terah: how many years before this time he was converted from idolatry cannot be said with any certainty; various are the accounts given by the Jewish writers; some say that at three years of age he knew his Creator; others at eight; others thirteen; others more probably when forty; others fifty one; others fifty two; and others say he was sixty years old when he began publicly to assert the unity of God in heaven (z): however, all agree it was before the age here mentioned, as it may well be concluded.

Removal to Canaan. - Abram cheerfully followed the call of the Lord, and "departed as the Lord had spoken to him." He was then 75 years old. His age is given, because a new period in the history of mankind commenced with his exodus. After this brief notice there follows a more circumstantial account, in Genesis 12:5, of the fact that he left Haran with his wife, with Lot, and with all that they possessed of servants and cattle, whereas Terah remained in Haran (cf. Genesis 11:31). עשׂוּ אשׁר הנּפשׁ are not the souls which they had begotten, but the male and female slaves that Abram and Lot had acquired.

So Abram departed, as the LORD had spoken unto him; and Lot went with him: and Abram was seventy and five years old when he departed out of Haran.

12:4 So Abram departed - He was not disobedient to the heavenly vision. His obedience was speedy and without delay, submissive and without dispute.

12:4,5 Abram believed that the blessing of the Almighty would make up for all he could lose or leave behind, supply all his wants, and answer and exceed all his desires; and he knew that nothing but misery would follow disobedience. Such believers, being justified by faith in Christ, have peace with God. They hold on their way to Canaan. They are not discouraged by the difficulties in their way, nor drawn aside by the delights they meet with. Those who set out for heaven must persevere to the end. What we undertake, in obedience to God's command, and in humble attendance on his providence, will certainly succeed, and end with comfort at last. Canaan was not, as other lands, a mere outward possession, but a type of heaven, and in this respect the patriarchs so earnestly prized it.
