Charles Ellicott Commentary Ruth 3:14

"And she lay at his feet until the morning. And she rose up before one could discern another. For he said, Let it not be known that the woman came to the threshing-floor." — Ruth 3:14 (ASV)

One could know another. —Literally, a man could recognize his friend; that is, before daylight, in the early dusk.

A woman. —Literally, the woman—that is, this woman. Thus it is of Ruth, not of himself, that Boaz is here thinking. A sensible man like Boaz knows “that we must not only keep a good conscience, but keep a good name; we must avoid not only sin but scandal.” (Henry.)
