Matthew Henry Commentary Genesis 13:1-4

"And Abram went up out of Egypt, he, and his wife, and all that he had, and Lot with him, into the South. And Abram was very rich in cattle, in silver, and in gold. And he went on his journeys from the South even to Beth-el, unto the place where his tent had been at the beginning, between Beth-el and Ai, unto the place of the altar, which he had made there at the first: and there Abram called on the name of Jehovah." — Genesis 13:1-4 (ASV)

Abram was very rich: he was very heavy, as the Hebrew word implies; for riches are a burden. And those who desire to be rich only load themselves with thick clay (Habakkuk 2:6). There is a burden of care in acquiring riches, fear in keeping them, temptation in using them, guilt in abusing them, sorrow in losing them, and finally, a burden of accountability for them.

Yet God in His providence sometimes makes good men rich, and thus God's blessing made Abram rich without sorrow (Proverbs 10:22). Although it is hard for a rich man to get to heaven, yet in some cases it is possible (Mark 10:23–24). Indeed, outward prosperity, if well managed, is an ornament to piety and an opportunity for doing more good.

Abram moved to Bethel. His altar was gone, so he could not offer sacrifice; but he called on the name of the Lord. You would as soon find a living man without breath as one of God's people without prayer.
