Genesis 13:14 - Clarke's commentary and critical notes on the Bible

And the LORD said unto Abram, after that Lot was separated from him, Lift up now thine eyes, and look from the place where thou art northward, and southward, and eastward, and westward: The Lord said unto Abram - It is very likely that the angel of the covenant appeared to Abram in open day, when he could take a distinct view of the length and the breadth of this good land. The revelation made Genesis 15:5, was evidently made in the night; for then he was called to number the stars, which could not be seen but in the night season: here he is called on to number the dust of the earth, Genesis 13:16, which could not be seen but in the day-light.
