Explanatory Notes on the Whole Bible, by John Wesley, [1754-65], at sacred-texts.com
gen 13:3He went on to Bethel - Thither he went, not only because he was willing to go among his old acquaintance; but because there he had formerly had his altar. and though the altar was gone, probably he himself having taking it down when he left the place, lest it should be polluted by the idolatrous Canaanites; yet he came to the place of the altar, either to revive the remembrance of the sweet communion he had had with God at that place, or, perhaps, to pay the vows he had there made to God when he undertook his journey into Egypt.
gen 13:6The land was not able to bear them - The place was too strait for them, and they had not room for their flocks.
gen 13:7And the Canaanite and the Perizzite dwelled in the land - This made the quarrel, Very dangerous; if Abram and Lot cannot agree to feed their flocks together, it is well if the common enemy do not come upon them and plunder them both. Very scandalous: No doubt the eyes of all the neighbours were upon them, because of the singularity of their religion, and the extraordinary sanctity they professed; and notice would soon be taken of this quarrel, and improvement made of it to their reproach by the Canaanites and Perizzites.
gen 13:10The garden of the Lord - That is, paradise.
gen 13:13Sinners before the Lord - That is, impudent daring sinners.
gen 13:16I will make thy seed as the dust of the earth - That is, they shall increase incredibly, and take them altogether; they shall be such a great multitude as no man can number. They were so in Solomon's time, Kg1 4:20. Judah and Israel were many as the land which is by the sea in multitude. This God here gives him the promise of.
gen 13:17Arise, walk through the land - Enter and take possession, survey the parcels, and it will appear better than upon a distant prospect.
gen 13:18Then Abram removed his tent - God bid him walk through the land, that is, Do not think of fixing in it, but expect to be always unsettled, and walking through it to a better Canaan; in compliance with God's will herein, he removed his tent, conforming himself to the condition of a pilgrim. And he built there an altar - in token of his thankfulness to God for the kind visit he had made him.
