John Gill Commentary Genesis 24:16

"And the damsel was very fair to look upon, a virgin, neither had any man known her. And she went down to the fountain, and filled her pitcher, and came up." — Genesis 24:16 (ASV)

And the damsel [was] very fair to look upon Of a good countenance and beautiful aspect: a virgin, neither had any man known her; not only was reckoned a virgin, but was really one, pure and incorrupt: and she went down to the well and filled her pitcher, and came up; by which it appears the well lay low, there was a descent to it, and an ascent from it.

Rebekah was very diligent and speedy in doing her work, she did not stay to look at strangers, or hold an idle conversation with other damsels that came there on the same account; but, having filled her pitcher, was making the best of her way home.
