And it came to pass at midnight
So long Boaz slept without knowledge of any person being at his feet, and so long Ruth had lain there; but awaking, and perceiving something at his feet, which pressed them, it made him look about and feel, and so affected him,
that the man was afraid;
though a man, and a man of spirit, he was afraid, a panic seized him, not knowing but it might be a spectre, a spirit, or a demon, as Jarchi; and such an instance we have in history
to see who it was:
a woman lay at his feet;
which he knew by putting his hand upon her head, as Jarchi thinks, and so knew her by her headdress, or vail; or rather by her voice, as Aben Ezra, and who supposes the moon might shine, and he might be able to discern she had no beard, as well as also discover her by her clothes.
