Their substance was great - As their families increased, it was necessary their flocks should increase also, as from those flocks they derived their clothing, food, and drink. Many also were offered in sacrifice to God.

They could not dwell together - 1. Because their flocks were great. 2. Because the Canaanites and the Perizzites had already occupied a considerable part of the land. 3. Because there appears to have been envy between the herdsmen of Abram and Lot. To prevent disputes among them, that might have ultimately disturbed the peace of the two families, it was necessary that a separation should take place.

And the land was not able to bear them, that they might dwell together,.... That part of the country where Abram and Lot were could not afford them room enough for their several tents; or however could not furnish them with sufficient pasturage for their flocks and herds, they were so numerous; at least could not do it so as to be contiguous to each other, that there was a necessity of one of them going further off:

for their substance was great, so that they could not dwell together; we have before an account of the substance of each of them, how great it was; and here now is noted an inconvenience which arises from a large increase of riches, that relations and friends are obliged to part, and cannot dwell together; what one would think would make them more comfortable together, is the cause and occasion of their separation.

And the land was not able to {c} bear them, that they might dwell together: for their substance was great, so that they could not dwell together.

(c) This inconvenience came by their riches, which break friendships and the bounds of nature.

13:6 The land was not able to bear them - The place was too strait for them, and they had not room for their flocks.

13:5-9 Riches not only afford matter for strife, and are the things most commonly striven about; but they also stir up a spirit of contention, by making people proud and covetous. Mine and thine are the great make-bates of the world. Poverty and labour, wants and wanderings, could not separate Abram and Lot; but riches did so. Bad servants often make a great deal of mischief in families and among neighbours, by their pride and passion, lying, slandering, and talebearing. What made the quarrel worse was, that the Canaanite and the Perizzite dwelt then in the land. The quarrels of professors are the reproach of religion, and give occasion to the enemies of the Lord to blaspheme. It is best to keep the peace, that it be not broken; but the next best is, if differences do happen, with all speed to quench the fire that is broken out. The attempt to stay this strife was made by Abram, although he was the elder and the greater man. Abram shows himself to be a man of cool spirit, that had the command of his passion, and knew how to turn away wrath by a soft answer. Those that would keep the peace, must never render railing for railing. And of a condescending spirit; he was willing to beseech even his inferior to be at peace. Whatever others are for, the people of God must be for peace. Abram's plea for peace was very powerful. Let the people of the land contend about trifles; but let not us fall out, who know better things, and look for a better country. Professors of religion should be most careful to avoid contention. Many profess to be for peace who will do nothing towards it: not so Abram. When God condescends to beseech us to be reconciled, we may well beseech one another. Though God had promised Abram to give this land to his seed, yet he offered an equal or better share to Lot, who had not an equal right; and he will not, under the protection of God's promise, act hardly to his kinsman. It is noble to be willing to yield for peace' sake.
