C. F. Keil and Franz Delitzsch on Genesis 13:8-9

Gen 13:8-9

To put an end to the strife between their herdsmen, Abram proposed to Lot that they should separate, as strife was unseemly between אחים אנשׁים, men who stood in the relation of brethren, and left him to choose his ground. “If thou to the left, I will turn to the right; and if thou to the right, I will turn to the left.” Although Abram was the older, and the leader of the company, he was magnanimous enough to leave the choice to his nephew, who was the younger, in the confident assurance that the Lord would so direct the decision, that His promise would be fulfilled.
